Resistor colour codes can sometimes be a little confusing until you understand how they work. But once you get the hang of them it becomes easier to read the values of those simple colour coded bands.
There is a lot of information both online and on this Electronics Tutorials website too, to help you read and understand how resistor colour codes work and this free, simple to use and practical resistor colour code wheel will hopefully help you on your way.
Generally, resistors are too small in size for manufacturers to print numbers and letters on them to indicate their resistive value and tolerance. Luckily for us, some bright spark somewhere invented a resistor colour coding system to make our lives easier and help us to work it out with our free resistor colour code wheel. Fixed resistors have different coloured rings or bands around them to indicate their resistive value with each coloured band having a decimal value associated with it.
