Resistor color code: How Does the Resistor Color Code Work

How Does the Resistor Color Code Work? Check out the All About Circuits Resistor Color Code Calculator, a handy tool for reading resistor color code values. Resistor values are often indicated with… Learn how to use the resistor color code to identify the resistance and tolerance of 3, 4, 5, and 6 band axial resistors. This resistor color code calculator lets you find any resistor value by simply choosing the color of each band. Or check out the table. With our resistor colour code calculator, you can get the answer you need in seconds, and without the risk of human error. Simply select the colours from your resistor (whether it’s a 4-band, 5-band, or 6-band resistor), and the calculator will instantly display the resistance value in ohms.
