Introduction

How to Use the Resistor Color Code Calculator

The online resistor calculator is a tool by ICSOEASY Electronic used to calculate resistor values for 4 band, 5 band, and 6 band resistors, in the range of ohms, Kilo Ohms, and Mega Ohms typically. And this resistance calculator is developed to calculate the color code using the resistor color codes on their surface.Just select the right color corresponding to each column and you can get the Resistor value on the right of the calculator immediately.

Frequently Asked Questions

1.How do you calculate resistor color code?

Hold the resistor with the gold or silver band to the right and read the color codes from the left to the right. Select the color codes from the bands on the resistor. Read the colors from left to right. The resistance value based on the color code provided is now displayed.
