1. What is different between series circuit and parallel circuit?
Eg) let’s take 4 bulbs and one battery (say the battery is 6Volts)
* Call the bulb A,B,C,D this are 4 bulbs now bulb (A )is connected to bulb (B) and bulb (B) is connected to bulb (c) and bulb (C) is connected to bulb (D) and bulb (D) is connected to battery this is called the bulb are connected in continues loop it is called series circuit.
* Again let’s take 4 bulb call them A,D,C,D and one battery so now
Bulb (A) is connect strait to the battery
Bulb (B) is connect strait to the battery
Bulb (C) is connect strait to the battery
Bulb (D) is connect strait to the battery
This is call each bulb are connected in a separate loop
And this is call parallel circuit.
If the four light bulbs are connected in series, there is same current through all of them, and the voltage drop is 1.5 V across each bulb, which may not be sufficient to make them glow. If the light bulbs are connected in parallel, the currents through the light bulbs combine to form the current in the battery, while the voltage drop is 6.0 V across each bulb and they all glow.
2. What is AC and DC
* (AC=alternating current)…(DC=direct current)
AC is an alternating current (the amount of electrons) that flows in both directions. In AC, electrons keep switching directions, sometimes going "forwards" and then going "backwards.
* DC is direct current that flows in only one direction… In DC, the electrons flow steadily in a single direction, or "forward.
3. What is resistance?
* This is resistance, which is measured in units called ohms. Resistance is a term that describes the forces that oppose the flow of electron current in a conductor. All materials naturally contain some resistance to the flow of electron current
* Resistance is anything that slows or stops movement or keeps movement from happening.
4. What is current?
Electric current is a flow...
