A resistor is identified by its pattern of color of bands. There are 4, 5 and 6 band resistors. To calculate the resistance of a resistor, you can select the appropriate color bands in the above resistor color code calculator.
How to calculate the resistance?
Just have a look to the resistor color code chart below and see the calculations, how the resistance value is calculated according to this chart.![](https://www.electronics-lab.com/wp-content/uploads/2022/11/Resistor-color-code-chart.png)
