This module will help you understand resistor colour coding and how to calculate the resistance of a resistor.

The value of most resistors is shown by a pattern of coloured bands. Each ring has a value. The colours are internationally defined as listed on the following pages.

Resistor colour codes

Objective

On completion of this module you will understand resistor colour coding, be able to calculate a resistors value and select a resistor of a specified resistance.
