Resistor Color Code and Tolerance

This video tutorial explains how to use the resistor color code to determine the value of a resistor. It covers the significance of each color band, how to calculate the resistance value, and how to account for tolerance. The video includes examples to illustrate the process, showing how to calculate the resistance and tolerance range for different color combinations.
