1. Experiment #1 Measurement of Resistance
Each student will be given a package of resistors.
For each resistor,
Determine the expected value of resistance by applying the color code (shown on page 3).
Measure the actual value of the resistance by using the ohmmeter function on the Digital Multimeter.
Compare the actual and expected values of resistance – does the actual value fall within the allowable range?
Enter your results in an EXCEL table, as shown on the next page.

2. Data for Resistance Experiment #1
Name:
Eg: Ohms
100*(Meas-Nom)/Nom
Determined from color band code

3. Resistor Color Band Code
Band 1 (closest to the end) – first digit
Band 2 – second digit
Band 3 – power of ten multiplier (most cases simply the number of zeros)
Band 4 – tolerance (Red = 2%, Gold = 5%, Silver = 10%, none = 20%)
