Resistor Calculator

Here is an easy online tool for calculating resistor values. It almost feels like cheating.

By spinning the wheel and matching up the colors your right on the money with the correct values.

Of course it might be a good idea to recheck the resistor with your meter to learn and get use to its general operation.
Another way to remember the colors on a resistor is the old saying "Bad Boys" etc. well you might know the rest but its not nice to talk about Violet that way.
Lets keep in clean.


  1. Good morning Jim, that is a very cool tool, when kit build I use my Fluke to check the values. If they are within the sorting bag they go. It's the inductors I have troubles with...can't measure them and sometimes the colors are hard to make out. Anyways nice program.

  2. I agree this is a great useful tool.
