4 Lectures 50:29

These four videos give the student a detailed description of their first electronics lab, where they will learn to:

1. Use the Resistor Color Code Chart to determine the expected resistance of resistors using color coded bands.

2, Use a multimeter to determine the actual resistance of that resistor.

3. Determine, using a tolerance formula, how close, as a percentage, the actual value of that resistor is to the expected value.
