Understanding Resistor Color Codes: What Do the Lines Represent and How to Identify Them?
This article explains the significance of resistor color codes and provides tips on how to identify them. The color bands on a resistor can convey important information such as resistance value, tolerance, and temperature coefficient. Knowing how to read these codes can help in selecting the right resistor for a circuit and troubleshooting potential issues. How to identify The lines on a resistor are known as color bands, and they represent the resistor’s value and tolerance. Resistors commonly have 4 bands and 5 bands, and we will explain using the 4-band system. To identify the resistor value, you need to look at the color of the bands. The first two…
