How to Read Resistor Color Codes | 4-Band Resistor Values and Tolerance

This lesson shows how to read common 4-band resistor color codes. It explains how the first two bands set the significant digits, how the third band gives the multiplier, and how the fourth band shows tolerance. The video also walks through practical examples so you can decode resistor values quickly and identify the correct bands for a target resistance. Useful for electronics, electrical training, and engineering technology students reviewing resistor basics.
