Experiment # 7
Resistance Calculation From Color Code & Verification Through Multi-Meter
Apparatus: Multi-meter, Battery, DC Power Supply, Jumper Wires, Breadboard, Color Code Chart, Function Generator.
|Resistance with Color Coding|
- Calculate the resistance of the available resistors by using color codes.
- Switch the selector of multi-meter to resistance measurement.
- Select the minimum range and measure resistance by connecting both probes of meter to the ends of resistors. Be sure, not to touch both ends of the resistor while the probes of meter are connected to the resistor. This will make a resistive path through your body in parallel with the resistor, thus affecting the correct reading. If the resistance of multi-meter pegged, i-e. Displays "1" on the left hand side of LCD display; this mean the resistance is greater than the selected range.
- Switch to the next available range and measure the resistance again.
- Repeat the procedure for different resistors available.
This is the simplest and easiest way to calculate the Resistance of a Resistor by its colors using color coding chart.
