# nLab infinity-group of units

### Context

#### Algebra

higher algebra

universal algebra

group theory

# Contents

## Idea

The generalization in (∞,1)-category theory of the notion of group of units in ordinary category theory.

## Definition

### Unaugmented definition

###### Definition

Let $A$ be an A-∞ ring spectrum.

For $\Omega^\infty A$ the underlying A-∞ space and $\pi_0 \Omega^\infty A$ the ordinary ring of connected components, write $(\pi_0 \Omega^\infty A)^\times$ for its group of units.

Then the ∞-group of units

$A^\times \coloneqq GL_1(A)$

of $A$ is the (∞,1)-pullback $GL_1(A)$ in

$\array{ GL_1(A) &\to& \Omega^\infty A \\ \downarrow && \downarrow \\ (\pi_0 \Omega^\infty A)^\times &\to& \pi_0 \Omega^\infty A } \,.$
###### Remark

In terms of derived algebraic geometry one has that

$GL_1(A) \simeq \mathbb{G}_m(A) = Hom(Spec A, \mathbb{G}_m)$

is the mapping space from $Spec A$ into the multiplicative group. This point of view is adopted for instance in (Lurie, p. 20).

### Augmented definition

There is slight refinement of the above definition, which essentially adds one 0-th “grading” homotopy group to $B gl_1(E)$ and thereby makes the $\infty$-group of units of E-∞ rings be canonically augmented over the sphere spectrum (Sagave 11).

###### Definition

There is a functor

$gl_1^J \colon CRing_\infty \to AbGrp_\infty/\mathbb{S} \,,$

given by …

This is (Sagave 11, def. 3.14 in view of example 3.8). See also (Sagave 11, section 1.4) for comments on how this yields an $\infty$-version of $\mathbb{Z}$-grading on an abelian group.

###### Proposition

For $E$ an E-∞ ring, there is a homotopy fiber sequence of abelian ∞-groups

$gl_1(E) \to gl_1^J(E) \to \mathbb{S} \,,$

where on the left we have the ordinary $\infty$-group of units of def. 1 and on the right we have the sphere spectrum, regarded (being a connective spectrum) as an abelian ∞-group.

Here the existence of the map $gl_1(E) \to gl_1^J(E)$ is (Sagave 11, lemma 2.12 + lemma 3.16). The fact that the resulting sequence is a homotopy fiber sequence is (Sagave 11, prop. 4.1).

Using this, there is now a modified delooping of the ordinary $\infty$-group of units:

###### Definition

Write $bgl_1^\ast(E)$ for the homotopy cofiber of $gl_1^J(E) \to \mathbb{S}$ to yield

$gl_1(E) \to gl_1^J(E) \to \mathbb{S} \to bgl_1^\ast(E) \,.$
###### Remark

It ought to be true that the non-connective delooping $bgl_1^\ast(E)$ sits inside the full Picard ∞-group of $E Mod$. (Sagave 11, remark 4.11). (Apparently it’s the full inclusion on those degree-0 twists which are grading twists, i.e. on the elements $(-)\wedge\Sigma^n E$.)

## Properties

### Adjointness to $\infty$-group $\infty$-ring

#### Unaugmented case

###### Definition

Write

$gl_1 \; \colon \; CRing_\infty \to AbGrp_\infty$

for the (∞,1)-functor which sends a commutative ∞-ring to its ∞-group of units.

###### Theorem

The ∞-group of units (∞,1)-functor of def. 4 is a right-adjoint (∞,1)-functor

$CRing_\infty \stackrel{\overset{\mathbb{S}[-]}{\leftarrow}}{\underset{gl_1}{\to}} AbGrp_\infty \,.$

This is (ABGHR 08, theorem 2.1/3.2, remark 3.4).

###### Remark

$\mathbb{S}[-] \colon AbGrp_\infty \to CRing_\infty$

is a higher analog of forming the group ring of an ordinary abelian group over the integers

$\mathbb{Z}[-] \colon Ab \to CRing \,,$

which is indeed left adjoint to forming the ordinary group of units of a ring.

We might call $\mathbb{S}[A]$ the spring ∞-group ∞-ring of $A$ over the sphere spectrum.

#### Augmented case

Also the augmented $\infty$-group of units functor of def. 2 is a homotopy right adjoint. (Sagave 11, theorem 1.7).

### Homotopy groups

The homotopy groups of $GL_1(E)$ are

$\pi_n(GL_1(E)) = \left\{ \array{ \pi_0(E)^\times & |\, n = 0 \\ \pi_n(E) & | \, n \geq 1 } \right.$

### Cohomology and logarithm

Given $E$ an E-∞ ring, then write $gl_1(E)$ for its $\infty$-group of units regarded as a connective spectrum. For $X$ the homotopy type of a topological space, then the cohomology represented by $gl_1(E)$ in degree 0 is the ordinary group of units in the cohomology ring of $E$:

$H^0(X, gl_1(E)) \simeq (E^0(X))^\times \,.$

In positive degree the canonical map of pointed homotopy types $GL_1(E) = \Omega^\infty gl_1(E) \to \Omega^\infty E$ is in fact an isomorphism on all homotopy groups

$\pi_{\bullet \geq 1} GL_1(E) \simeq \pi_{\bullet \geq 1} \Omega^\infty E \,.$

On cohomology elements this map

$\pi_q(gl_1(E)) \simeq \tilde H^0(S^q, gl_1(E)) \simeq (1+ \tilde R^0(S^q))^\times \subset (R^0(S^q))^\times$

is logarithm-like, in that it sends $1 + x \mapsto x$.

But there is not a homomorphism of spectra of this form. This only exists after K(n)-localization, where it is called then the logarithmic cohomology operation, see there for more.

(Rezk 06)

### Relation to Picard $\infty$-group and Brauer $\infty$-group

Given an E-∞ ring $E$, the looping of the Brauer $\infty$-group is the Picard ∞-group (Szymik 11, theorem 5.7).

$\Omega Br(E) \simeq Pic(E).$

The looping of that is the ∞-group of units (Sagave 11, theorem 1.2).

$\Omega^2 Br(E) \simeq \Omega Pic(E) \simeq GL_1(E) \,.$

## Examples

### Snaith’s theorem and the units of K-theory and complex cobordism

Snaith's theorem asserts that

1. the K-theory spectrum for complex K-theory is the ∞-group ∞-ring of the circle 2-group localized away from the Bott element $\beta$:

$KU \simeq (\mathbb{S}[B U(1)])[\beta^{-1}] \,;$
2. the periodic complex cobordism spectrum is the ∞-group ∞-ring of the classifying space for stable complex vector bundles (the classifying space for topological K-theory) localized away from the Bott element $\beta$:

$MU \simeq (\mathbb{S}[B U])[\beta^{-1}] \,.$

### Units of topological modular forms

Analysis of the $\infty$-group of units of tmf is in (Ando-Hopkins-Rezk 10, from section 12 on).

### Inclusion of circle $n$-bundles into higher chromatic cohomology

By Snaith’s theorem above there is a canonical map

$B U(1) \to \mathbb{S}[B U(1)] \to KU$

that sends circle bundles to cocycles in topological K-theory.

At the next level there is a canonical map

$B^2 U(1) \to \mathbb{S}[B^2 U(1)] \to tmf$

that sends circle 2-bundles to tmf. See at tmf – Inclusion of circle 2-bundles.

Write $gl_1(K(n))$ for the ∞-group of units of the (a) Morava K-theory spectrum.

###### Proposition

For $p = 2$ and all $n \in \mathbb{N}$, there is an equivalence

$Maps(B^{n+1}U(1), B gl_1(K(n))) \simeq \mathbb{Z}/(2)$

between the mapping space from the classifying space for circle (n+1)-bundles to the delooping of the ∞-group of units of $K(n)$.

###### Remark

By the discussion at (∞,1)-vector bundle this means that for each such map there is a type of twist of Morava K-theory (at $p = 2$).

## swimlife97 one year ago If you are given time and distance, you can determine power if you know force. watts. energy. joules.

1. theEric

Well, watts are the units of power, and joules are the units of energy, and this question isn't going for you knowing units. It wants you to know which physical concept is missing from knowing the power. You're down to "force" or "energy." Do you have a guess and a reason?

2. theEric

Hint:$P=\frac{W}{t}$

3. theEric

Want another hint?

4. swimlife97

5. theEric

Okay!$W=F\ d\ cos(\theta)$Put that in the power equation, if you need another hint.

6. swimlife97

Is it force?

7. theEric

Why do you guess "force"?

8. swimlife97

W=F d cos(θ) W is work in Joules; F is force through distance; Cos theta is cosine of an angle theta

9. theEric

So, you say the answer is force because, well, you need it. And I agree, you're totally right.

10. theEric

$P=\frac{W}{t}=\frac{F\ d\ cos(\theta)}{t}$so you know distance and time, you just need force. The equations can be telling!

11. swimlife97

Okay thank you :)

12. theEric

You're welcome! :)

And congrats, because you did it! I just posted equations, haha.

Dual Electrode Electrolysis (DEBE)

1Technique Overview

Dual Electrode Electrolysis (DEBE) is both a galvanostatic and potentiostatic method, depending on user choice of electrode mode.  The background and theory of this method is closely related to its single electrode version, Bulk Electrolysis (BE), however by employing a bipotentiostat, two working electrodes undergo an electrolysis simultaneously.

Many techniques used in electroanalytical chemistry affect change within a chemical system with small surface area to volume ratios.  For example, it is common to conduct stationary cyclic voltammetry (CV) at a 3 mm OD working electrode in 100 mL of solution containing  1 mM electroactive species.  In such a system, CV can be performed for long periods of time without appreciably changing the bulk concentration of analyte (oxidized and or reduced species), assuming a nominal 1 mA/cm2 current density.  In this case, <1 C passes and the bulk concentration of electroactive species does not appreciably change (~250 mC).

Many techniques used in electroanalytical chemistry affect change within a chemical system with small surface area to volume ratios.  For example, it is common to conduct stationary cyclic voltammetry (CV) at a 3 mm OD working electrode in 100 mL of solution containing  1 mM electroactive species.  In such a system, CV can be performed for long periods of time without appreciably changing the bulk concentration of analyte (oxidized and or reduced species), assuming a nominal 1 mA/cm2 current density.  In this case, <1 C passes and the bulk concentration of electroactive species does not appreciably change (~250 mC).

In contrast to this typical setup, Dual Electrode Electrolysis (DEBE) is conducted with large surface area to volume ratios and often convective stirring for enhanced mass transport.  The anticipated outcome is to significantly change bulk solution properties during the course of the electrolysis.  Unlike typical CV experiments, DEBE working and counter electrodes are 2 - 4 orders of magnitude larger in area; thus, for a larger working electrode with A = 100 cm2 and the same 1 mA/cm2 current density, >350 C passes through the cell.  In this case, all electroactive species in the cell are converted to their reduced form in a short period of time.  Often, this is the goal to exhaustively convert analyte from reduced to oxidized form, and vice-versa.

DEBE is often performed in a separated cell, consisting of either two or three chambers, each separated by a porous material like sintered glass disks (frits) or polymer exchange membranes (e.g., Nafion®).  The working (WK1 and WK2 are typically separated) and reference electrodes are often placed into one chamber of a separated cell and the counter electrode in another.  The working electrode chambers should be stirred to provide maximum mass transport to the electrode during electrolysis.  Some electrolysis cells separate each electrode into their own separate chamber. Both the working and counter electrodes should have a large surface area (typically platinum meshes or high surface area carbon meshes, foam, felts and vitreous carbon materials) to increase current (charge) and reduce time to reach exhaustive electrolysis.

Bulk electrolysis can be operated with four different electrode modes:

• controlled potential (POT), where a constant potential is applied and current vs. time is measured
• controlled current (GAL),  where a constant current is applied and potential vs. time is measured
• zero resistance ammeter (ZRA), where potential is actively driven to 0 V and current vs. time is measured
• open circuit potential (OCP), where the counter electrode is bypassed such that no current passes and voltage vs. time is measured

Controlled potential bulk electrolysis is by far the most commonly used mode; however, some might use controlled current for select applications.  While a potentiostat, with reference feedback, is required for controlled potential bulk electrolysis, simpler instrumentation consisting of only a high voltage power supply (or batteries) and a large resistor can be used.  The focus of this article will primarily focus on DEBE in POT mode (constant potential bulk electrolysis) for both working electrode 1 (WK1) and working electrode 2 (WK2).

2Fundamental Equations

Numerous texts thoroughly explain electrochemical theory and should be consulted for a complete understanding of this method.

Consider the general reaction

$\displaystyle O+ne^- \rightleftharpoons R$

where $O$ is reduced to $R$ in a one electron reaction.  A solution of $m$ moles of $O$ would require $m$ moles of electrons to completely reduce $O$ to $R$.  Upon applying a sufficient reducing potential, a large amount of $O$ is converted to $R$ and subsequently swept away from the rotating electrode.  As more $O$ is converted to $R$ the current falls off exponentially until it reaches background level.  It is at this point, the electrolysis can be stopped.  The charge $(Q)$ passed during the experiment can be obtained by integrating the current with respect to time.

$\displaystyle Q = {\int}i(t)dt$

By the following equation, charge can be converted to the number of moles of $O$ electrolyzed during the experiment

$\displaystyle m = \frac{Q}{Fn}$

where $F$ is Faraday's constant (96,485 C/mol) and $n$ is the number of electrons transferred during the reaction.  This analysis is conducted for each chronoamperogram (i.e., separately for WK1 and WK2).

Additional and more complete background of this theory is provided in the Theory section of the Knowledgebase.

3Experimental Setup in AfterMath

To perform a dual-electrode electrolysis experiment in AfterMath, choose Dual Electrode Electrolysis (DEBE) from the Experiments menu (see Figure 1).

Figure 1. Dual Electrode Bulk Electrolysis (DEBE) Experiment Menu Selection in AfterMath

Doing so creates an entry within the archive, called DEBE Parameters. In the right pane of the AfterMath application, several tabs will be shown (see Figure 2).

Figure 2. Dual Electrode Electrolysis (DEBE) Experiment Basic Tab

Continue reading for detailed information about the fields on each unique tab.

3.1Basic Tab

The basic tab contains fields for the fundamental parameters necessary to perform a BE-RDE experiment.  AfterMath shades fields with yellow when a required entry is blank and shades fields pink when the entry is invalid (see Figure 3).

Figure 3. Dual Electrode Electrolysis (DEBE) Parameters Basic Tab

The description that follows describes the fields and steps for DEBE.  Realize that these steps apply to either WK1 or WK2 and are the same for either electrode.  Both WK1 and WK2 settings are applied simultaneously.

The first selection with DEBE is the Electrode mode (see Figure 3).  Controlled potential DEBE for both WK1 and WK2 electrodes is the most commonly used mode.  The modes available are summarized as follows:

• Controlled Potential (POT), where a constant potential is applied and current vs. time is measured
• Controlled Current (GAL),  where a constant current is applied and potential vs. time is measured
• Zero Resistance Ammeter (ZRA), where potential is actively driven to 0 V and current vs. time is measured
• Open Circuit Potential (OCP), where the counter electrode is bypassed such that no current passes and voltage vs. time is measured

As with most Aftermath methods, the experiment sequence is

Induction Period → Electrolysis Period → Relaxation Period → Post-Experiment Idle Conditions

This sequence is applied to both WK1 and WK2 simultaneously.  Unlike most experiments, the Induction and Relaxation Periods are on the Basic Tab.  The parameters for a DEBE experiment are fairly simple compared to other methods in AfterMath.  A plot of the typical experiment sequence, containing labels of the fields on the Basic tab, helps to illustrate the sequence of events in a DEBE experiment (see Figure 4).  Again, given that different electrode modes are possible, the illustrations provided here assume Controlled Potential (POT) mode; however, other modes such as Controlled Current (GAL) are analogous to these figures, with different units on the y-axis.

Figure 4. Dual Electrode Electrolysis (BE) Basic Tab Field Diagram

The field diagram (see Figure 4) shows the parameters for a single electrode.  The diagram applies to both WK1 and WK2; however, each electrode has their own separate settings on the basic tab.

Field labels in AfterMath will eventually include symbols, such as those used in the waveform plot below.  Consult the cross-reference table (see Table 1) to match field names with symbols.

 Group Name Field Name Symbol Induction Period Potential $E_{IND}$ Induction Period Duration $T_{IND}$ Electrolysis Period Potential $E_{E}$ Electrolysis Period Duration $T_{E}$ Relaxation Period Potential $E_{RLX}$ Relaxation Period Duration $T_{RLX}$ Sampling Control Number of Intervals $N_{INT}$
Table 1.  Basic Tab Group Names, Field Names, and Symbols.

During the induction period, a set of initial conditions are applied to the electrochemical cell and the cell equilibrates at these conditions at each working electrode.  Data are not collected during the induction period, nor are they shown on the plot during this period.

After the induction period, the potential applied to each working electrode is stepped to the specified value for the duration of the experiment, which is called the electrolysis period.  The potentiostatic circuit of the instrument maintains constant applied potential relative to the reference electrode while simultaneously measuring the current at the working electrodes.  During the electrolysis period, potential and current at the working electrodes are recorded at regular intervals as specified on the Basic tab.  Sampling control defines the number of intervals (number of data points) collected during the electrolysis period.  With Electrolysis period duration, a sampling rate can be defined as,

$\displaystyle {\textrm{sampling rate}=\frac{\textrm{number of intervals}}{\textrm{electrolysis period duration}}}$

Users should enter a number of intervals that their analysis requires.  Commonly, BE experiments are sampled at a lower rate (1 sample/s).  Not all sampling rates are allowed due to differences in hardware (WaveNow series vs. WaveDriver series, for example).

NOTE:  Not all sampling rates are possible.  When users enter a number of intervals that is not allowed, AfterMath will prompt the user with an "Interval too short" error.  Change the number of intervals and try again.  In general, integer values at moderate rates are most often possible.

The experiment concludes with a relaxation period.  During the relaxation period, a set of final conditions (specified on the Advanced tab) are applied to the electrochemical cell and the cell equilibrates at these conditions.  Data are not collected during the induction period, nor are they shown on the plot during this period.

At the end of the relaxation period, the post-experiment idle conditions  are applied to the cell, for each working electrode WK1 and WK2, and the instrument returns to the idle state.  The default plot generated from the data is measured potential vs. time, called a chronoamperogram.  The chronoamperogram will contain two traces, one for each working electrode (as indicated by the plot legend).

The Electrode Range on the Basic tab is used to specify the expected range of current and/or potential.  If the choice of electrode range is too small on a potentiostatic experiment, measured current could be off-scale, appearing as a truncated flat line where the signal exceeded the selected measurement range.   Alternatively, if the electrode range is too large for the incoming signal, measured current may have a noisy, choppy, or quantized appearance due to lower than desirable resolution based on range choice.  More details on avoiding "the ugly ducking" within the knowledgebase.

The BE Advanced tab contains two groups for iR Compensation and for Experiment End Trigger for both WK1 and WK2 (see Figure 5).

Figure 5. Dual Electrode Electrolysis (DEBE) Parameters Advanced Tab

Detailed description of the iR Compensation Mode is provided elsewhere on the knowledgebase.  This mode is used to correct for uncompensated resistance in the electrochemical cell.

In a DEBE experiment, the researcher may want to have AfterMath monitor the response and then stop the experiment a specific current, potential, and/or charge.  This value is called a trigger and is set in the Experiment End Trigger group on the Advanced tab (see Figure 5).  There are independent triggers available for either WK1 and/or WK2.  For DEBE, the signals for the trigger can be potential, current, or charge based on the Electrode Mode selected on the Basic tab (see Figure 3).  A common example of using this trigger is in the charging of a battery.  A researcher would charge the battery by performing a DEBE Controlled Currrent (GAL) mode selected (also called a CC or constant current)  with the trigger set to its upper potential limit (e.g., 100% SOC).  Once this potential limit is reached, the DEBE experiment terminates and retains the data collected up to the trigger endpoint.

Another application is in the plating process.  If a user wishes to control the deposition layer thickness on a working electrode, they might use a constant potential to drive the reduction at the electrode.  In this case, a user may have calculated a theoretical mass they intend to plate to an electrode.  Through Faraday's Law (see Section 2), the user can calculate the total charge that must pass to yield the desired mass on the electrode surface.  In this case, a user may set an Experiment End Trigger to stop DEBE (at the specfied electrode(s)) after passing this amount of charge.  Details on the End Trigger settings are found elsewhere in the knowledgebase.

3.3Ranges, Filters, and Post Experiment Conditions Tab

The Filters tab provides access to potentiostat hardware filters, including stability, excitation, current response, and potential response filters.  Pine Research recommends that users contact us  for help in making changes to hardware filters.  Advanced users may have an easier time changing the automatic settings on this tab.  Filter settings fields are shown for WK1 (working electrode #1) as well as for WK2 (working electrode #2) regardless of the potentiostat connected to AfterMath.  More information on filters is available elsewhere on the knowledgebase.

By default, the potentiostat disconnects from the electrochemical cell at the end of an experiment.  There are other options available for what these post-experiment conditions can be and are controlled by setting options on the Post Experiment Conditions tab.  Complete details on the fields and settings on this Post Experiment Conditions tab are provided elsewhere on the knowledgebase.

# How to change ordinal X-axis label to text labels using ggplot2 in R?

A plot created with ordinal values on X-axis needs to be ordered for plotting, otherwise, the plot will have continuous values on the X-axis that includes ordinal values. If we want to convert those values to text then scale_x_discrete should be used with the number of breaks, these number of breaks are the actual number of labels we want to use in our plot.

## Example

Consider the below data frame −

x<-1:3
Quantity<-c(515,680,550)
df<-data.frame(x,Quantity)
library(ggplot2)
ggplot(df,aes(x,Quantity))+geom_point()

## Output

Plotting text labels on X-axis in place of numbers −

ggplot(df,aes(ordered(x),Quantity))+geom_point()+
+ scale_x_discrete(breaks = 1:3, labels=c("Small","Medium","Large"))+
+ xlab(NULL)

A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.

Since lines l and m are parallel. we know that x + y = 180

So, one option is to replace Quantity B with x + y to get:
QUANTITY A: x + 2y
QUANTITY B: x + y

At this point, it may seem obvious that Quantity B is greater.
If it's not obvious, we can continue by applying the matching operations strategy

Subtract x from both quantities to get:
QUANTITY A: 2y
QUANTITY B: y

Subtract y from both quantities to get:
QUANTITY A: y
QUANTITY B: 0

Since y must have a POSITIVE value, Quantity A is greater

Understanding The Gate Of A MOSFET MOSFETs are remarkable devices which provide many benefits when driving various loads. The fact that they are voltage driven and that, when on, they have very low resistances make them the device of choice for many applications. However, how the gate actually works is probably one of the least understood characteristics ...

If you selected this driver, which has huge output current (7A) then I presume you need this gate drive current to switch a very large FET very fast. The gate resistor will only slow things down by reducing gate drive current, so its optimum value is zero ohms. Its maximum value depends on acceptable switching losses (switching slower causes more switching ...

17

I've answered a question very similar to this here (How do I design correctly ground plane separation for Texas Instruments TPS63060 IC?), but I'll tweak a reply for you here. IRF is asking you to keep those grounds "separate" in the sense that they do not want (as an example) 5A of current flowing through the output switches/stages to perturb the ground ...

First off, the rules of the site do state not to ask for recommendations of products, so I will skip that bit. Just read the datasheets as everything will be explained in there. If there is something on a datasheet you do not understand, please post a separate question about it. Now, on to your problem. From what I think you are trying to do, you may find ...

Holy Carp! You're trying to do 10's of nsec switching on a solderless breadboard? And you don't have a flyback diode on your transformer? If you're going to do this stuff, you've got to learn to respect fast switching and inductive parasitics. Go to a ground plane and make all your switching paths as short as possible. Also, put a 100 uF cap (tantalum for ...

These transistors don't conduct unless Vbe>0.6V for the NPN, Vbe<-0.6V for the PNP. And as the bases and emitters are tied together, it is impossible for both these conditions to be true at the same time. So when one transistor is turned on, the other is turned off. HOWEVER if R2 is too low, the transistor being turned on will "saturate". And when ...

15

Lose the diode. I can't even guess what you think it does, but it will prevent the FET from being turned off quickly. The FET driver will drive the gate high quickly, which turns on the motor. However, when it tries to drive the gate low, the diode prevents it from doing so. That means the gate just floats. It probably slowly drifts low, running the FET ...

14

This is indeed an interesting problem, because of the variation of effective load capacitance with the load resistance due to Mr. Miller, and your need to not overcompensate it. I suspect a biased push-pull BJT output driver would work fine- maybe 4 small BJTs (2 connected as diodes) a couple bias resistors plus maybe a couple ohms each of emitter ...

14

The trouble with using a high side P channel MOSFET driven from a signal that doesn't get close (less than 0.5 volts) to the high side voltage is that there is a decent probability that it will appear to be still active when you believe you have it turned off. However, with some care you can put a zener diode in series with your 3.3 volt GPIO drive voltage ...

14

which is best for fast switching do I need to use MOSFET driver IC such as ICL766 with IRFZ44n or is it better to use lower VGS MOSFET such as AO3400 You don't want fast switching to drive LED strips! If the FET switches in a couple tens of nanoseconds, you will send very high di/dt currents into your wires which will radiate electromagnetic interference ...

13

Here is your circuit being discussed: R3 and R5 should not be getting "hot". Do the math. Even if Q1 were a perfect switch, there would only be 5 V across R3. (5 V)2(1 kΩ) = 25 mW. Unless this is a very tiny resistor, you wouldn't normally notice it getting warm. A 0805, for example, can usually dissipate about 150 mW safely in open air on a ...

12

Figure 1. When Q1 is off both Q2 and Q3 are forward biased (green) and will turn on. The result will be shoot-through the two transistors (red). If the supply voltage doesn't collapse (1) will be at about 4.3 V, (2) at 2.5 V and (3) at 0.7 V. Ignoring R3 the current through Q2, R4, R5 and Q3 will be about $\frac {5 - 0.7=0.7}{2k} = 1.8 \ \text {mA}$. I ...

11

In a true totem pole configuration, shoot thru usually does occur for a very short time during switching. However, what you have is not a totem pole configuration. You have two emitter followers back to back. In this case, you will not get shoot thru. For each transistor to be on, the base has to be one junction drop towards the collector voltage from ...

Here is another approach that uses an N-MOSFET in a level shifter configuration that does not invert the control signal polarity. simulate this circuit – Schematic created using CircuitLab You need to chose MOSFETs with under 1V gate thresholds, M1 needs to be low Rds-ON. M2 can be a small signal device.

To protect against possible future edits, here is the circuit we're talking about: Major problem are: There are no component designators in the schematic, making the circuit hard to talk about. The 1 mF cap makes absolutely no sense. You have a double emitter follower driving the FET gate. This provides substantially more current capability than the ...

On your layout the decoupling cap (finger-painted red) is very far away from the chip, there is a 5R resistor in series (purple) and the current loop area (highlighted in yellow) is quite large. This large loop area adds inductance to the power supply impedance as seen from the chip. Wet finger in the wind, about 10-20 nH. With a di/dt around 1A per 1-2ns ...

They got destroyed due to inductive kickback. The TVS diode is not a correct choice, you should use a schottky diode at that position. When the MOSFETs were switched off, the motor induced a high voltage, that was clamped with TVS, but these devices are meant to surge a short pulse, not to dump entire motor energy, so it has blown, consequently MOSFETs also ...

A combination of the IRF840's reverse transfer capacitance (120pF), the dv/dt of the drain voltage and the rather weak driver (MCP1402) is my best guess. Starters, read the data sheet on the driver - it says on page 3 that the "latch-up protection withstand reverse current" is typically greater than 0.5 amps - that is a clue to why that device might be ...

Outcome Report Okay, the short story is: adding a discrete buffer worked! That said, I don't think I'll design my circuit this way, rather I'll go with the recommendation of @Spehro and @WhatRoughBeast and just use an op amp with higher current output capability, basically having the buffer stage built right into the op amp. Here's the circuit I used. ...

Sometimes... Assuming the point of interest is power MOSFETS and not small signal MOSFETS and silicon (as oppose to SiC, GaN) The first characteristic to check is the output voltage.

There is nothing wrong with driving a FET like this if there is no need to PWM. What I would add is Add a series gate resistor ( ~100R) consider adding a 15V zener gate-source just incase there are some transients. You do not want to burn the gate region out NOTE: you might want something bigger than just a Zener on the gate. TVS maybe. its dependent ...

That is a pretty weird way of "driving" LEDs. OP's schematic: A few issues: essentially you have an "equivalent" resistor, shared by the LEDs (if the LEDs have any imbalance - which they have - the current draw will be uneven) power draw - when the LEDs are "off", the FET will be drawing the current (even more than the amount ...

This is no easy task to do by simply re-using bits of old motherboards. It's a problem that I feel requires a properly designed solution. I can't imagine that the laser diodes are cheap and because of this I would recommend a properly designed circuit board with a design solution that is tailored for this application. I'm initially thinking of maybe the ...

8

No. The datasheet tells you what the bare part can do, already assuming very fast gate transistions. The test conditions are usually listed in the datasheet. Read it.

8

Either choose a better MOSFET or use a push-pull driver like this: - Notice that this chip uses identical MOSFETs in the output stage. Here's another using the FAN7842 from Fairchild: - You should also make sure there is enough deadtime between one turning off and the other turning on. Both devices can be used to drive single MOSFET outputs if needed. ...

Your BJTs are in a follower configuration. This means that they can provide current gain, but not voltage gain. In fact the emitters will be a diode drop BELOW the base for positive going signals. If you got to 6V on the gate you must have had around 6.7V out of your signal generator. The BJT Wiki page has links to the 3 common forms of amplifier which ...

8

The circuit you show should work. You probably don't have something connected correctly. For example, if the drain and source of the FET were flipped, you'd get exactly the symptom you see due to the body diode of the FET conducting. Check the FET datasheet and your connections carefully. Measure the gate voltage with a voltmeter, and verify that it ...

8

There's a continuous base current path for both Q2 and Q3 when Q1 does not conduct. You can easily expect continuous 200mA current through them from your +5V. That's about 1W dissipation which well can make also other parts behind short wires hot than Q2, Q3. Thermal runaway can short your +5V source.

7

You should look at the I-V curves specified for the device. The first plot refers to IRF520. As you can see, you need at least 4.5V on the gate in order to get a current just a bit higher than 1A. With 3.3V the current could be even lower than 1A. (I can't tell from the graph, but I'm quite sure this device isn't going to work with your setup). In the case ...

If p is a positive integer, for what minimum value of p is $$7∗10^{p}+4p$$ divisible by 9?

$$7∗10^{p}+4p= 7∗(9+1)^{p}+ 4p= 7∗(9^{p}+ 9^{p-1}+...+1)+4p= ( 7∗9^{p}+ 7∗9^{p-1}+...+7 )+ 4p$$

Now, we need to check 7+ 4p whether it is divisible by 9.

A) if p=3, then 7+4∗3= 19 (not divisible by 9)
B) if p=5, then 7+4∗5= 27 (divisible by 9) -Correct

We know that 10 divided by 9 leaves remainder 1
=> $$10^p$$ divided by 9 leaves remainder 1 as well
(Any positive integer power of 10, if is divided by 9, the remainder is 1)

=> $$7 * 10^p$$ divided by 9 leaves remainder 7 * 1 = 7

Since $$7 * 10^p + 4p$$ is divisible by 9, we have:

The remainder when $$7 * 10^p + 4p$$ is divided by 9, the remainder is 0

=> The remainder when 4p is divided by 9 must be 2
(Since $$7 * 10^p$$ has remainder 7; and 2+7= 9, i.e. remainder is 0)

At p = 5, i.e. 4p = 20, the required remainder becomes 2.

For an integer to be divisible by 9, the sum of digits of the integer should be divisible by 9

A. 3
$$7 * 10^p + 4p$$ = 7000+12=7012

7+0+1+2 = 10 - Not divisible by 9

We need the sum of the digits of x 10^p + 4p to be a multiple of 9. Since we are looking for a minimum value of p, let’s check the values in the given choices from the smallest to the largest.

A. 3

7 x 10^3 + 4(3) = 7000 + 12 = 7012

The sum of the digits is 10, which is not a multiple of 9, so A is not the correct answer.

B. 5

7 x 10^5 + 4(5) = 700,000 + 20 = 700,020

Since the sum of the digits is 9, B is the correct answer.

The fastest way to solve this problem in under 1 minute is to test the answers. For this, we will need to know some basic rules of divisibility. A number is dividisble by 9 if the SUM of its DIGITS is divisible by 9.

Since we are asked to find the minimum value, I will start by testing the lowest numbers first.

Let's try option A.
7 * 10^3 + 4*3 = 7000 + 12
The sum of the DIGITS is 10 (7+1+2)
10 is not divisible by 9.
Let's move on to the next answer option.

Let's try option B.
7 * 10^5 + 4*5 = 700,000 + 20
The sum of the DIGITS is 9 (7+2)
9 is obviously divisible by 9.

centering a table row height How to change row height of tables in LaTeX. This works well as long as the content in each cell is short and of similar length. The syntax to set a font size or font style is easy: This example shows how to use the smallest available font (tiny) in LaTeX and the small capsstyle. You may also be interested in multi-row and multi-column cells in tabular/table, which was previously covered. Example code might look like: Note the colwidths option which is telling it to set the first column to 0.3 or 30% of the width of page. Use the scale=1.5 option in the \includegraphics command to resize the image to 150% of its original size. The minimum width of each column. You do that by adding \arraybackslash to the last column declaration after the last alignment modifier. Table and column widths are set by the widths of the table and col elements or by the width of the first row of cells. If you want to have an exact width to table cells of different tables then first understand the following description. Only for LaTeX tables. First set "word wrap" on, then set "auto-size" off, it would satisfy your scenario. We can use pre- and post-column-type declaration. The columns format as specified in LaTeX table format e.g. You can define a different width for every column so that it fits nicely. Instead, you have to use the colspan attribute to overlap cells on different rows. A HTML only feature to contoll whether the header row will be manipulated. Asked 3rd Jan, 2020; ... My equation is exceeding the column width and the equation label is miss aligned. 2. online LaTeX editor with autocompletion, highlighting and 400 math symbols. Regarding Latex single column format in double column paper. Three Columns: 1.83″ width for each column, with a 0.5″ space between columns. entry. 3cm / 2in) or as a fraction of the text width (e.g. Is the content in the two columns separate or a continuous text? between text and the columns, it can be inserted with the command \hspace{}. To achieve automatic balancing of columns, take a look at the tabulary package. ... To change only one particular row you could use the command \rule with a width of zero and the height you want as … The floating environments figure* and table* allow adding wide, single-column tables or figures in a two- or multicolumn document.. The second row will have td, td colspan=2, td and so on. Now that we've setup our table properly, we can focus on adding more rows and columns. There are three macros for left, center and right alignment, listed in the table below. The array package further implements the macro \newcolumntype{name}{definition}, which offers a simple way to define your own column types and use them throughout the document. ‘rcl’ for 3 columns. Note that this example requires additional packages to be loaded (xcolor and colortbl). The tables in LaTeX can be created using the table environment and the tabular environment which uses ampersands (&) as column separators and new line symbols (\\) as row separators. This significantly shortens the column-type declaration, especial when using the array package column-types with pre- and/or post-column-type declarations. Export (png, jpg, gif, svg, pdf) and save & share with note system The column values used are based on widths defined on columns or cells for the first row of the table. In addition, you can set the widths of your TABLE columns to display your columns at a specific width. At this point it thinks that the rst two columns are very narrow. Open an example in Overleaf However, often you want to display several words or even complete sentences and the text might run into the margins. (see example below) The workaround with a leading 0 does the job for the moment. The widths of the table and its cells are adjusted to fit the content. (adsbygoogle = window.adsbygoogle || []).push({}); Need help with your thesis or book project? That is, \includegraphics[width=50mm,scale=1.5]{method.eps}. The column definition at the beginning of a tabular tends to get rather lengthy. One option is to use the commands \setlength and \arraystretch to change the horizontal spacing (column separation) and the vertical spacing (row separation) respectively. But what you want is to define fixed width columns. If you forget to add \arraybackslash, you will get an error (Extra alignment tab has been changed to \cr). 3cm / 2in) or as a fraction of the text width (e.g. inherit : indicates that the value is inherited from the table-layout value of its parent In order for a value of fixed to have any effect, the table’s width has to be set to something other than auto (the default for the width property). This is where the additional column-types p, m and b come in. If you wish to have a table where each cell in a row has the same width, you would use the p option instead of l, c or r for left, centre or right alignment.. Be aware that the way tabularx parses the con-tents of a table limits the possibility of de ning new In order to do so, three different Latex commands are used… Whole document (using article to … 3. Below you can see the simplest working example of a table The tabular environment is the default LaTeX method to create tables. These help making tables more readable. It's quite messy - you might want to consider displaying your data in a different way, for example, using DIVs T/F. Write out the column names. But more often, we are concerned with the horizontal alignment. In the example below I use the latter. latex_column_spec. Let’s discuss. The reason I used 20 columns was because I imagined he might need another configuration of columns, not just the 25-50-25 and 50-30-20 he uses now, and I found the 20-column example a bit easier to understand, although indeed messier. All the width of the multicolumn entry is assumed to be in the third column. In order to elimi- Rather than using c or l or r to define the columns of the table, use p{width} which will create a column width wide where you can input a paragraph of text. You might wonder how to horizontally align the content in each column. As I've mentioned before, LaTeX uses column separators (&) and row separators (\\) to layout the cells of our table. longtable then passes the information that there is a wide third column to the later chunks, with the result 2. Multi-column and multi-row cells in LaTeX tables, Control the width of table columns (tabular) in LaTeX, Lists: Enumerate, itemize, description and how to change them. Once the package is imported, the environment multicolscan be used. See above for an example. Set HTML Table Column Widths as a Percentage. Default is FALSE. Code to replace the column specification. You can do this quite easily with the parcolumns package. When you create a table with a repeated column-type, you can use the short form: *{n}{type}. Either we want the whole document to have two columns, single pages or only part of a page. LATEX, simple columns that are either centered or aligned left or right always automatically calculate their width based on the content of the cells. Here is a somewhat extreme example with a paragraph of dummy text (blindtext package) added to the first row of the second column. Example: extra_css.
