Calculate Resistance with our Resistor Calculator

Hey folks – I decided to learn some electronics at long last, and so with the help of Getting Started in Electronics by Forrest M. Mims III, I’m building some guitar FX projects. Takes me back to my dinky little electronics project kit with the spring connections and that medical-looking flesh-colored crystal earphone/microphone, except now I have a rudimentary understanding of how electricity works…

To help me out when sorting my resistors, I built this little tool to save me consulting the table in GSiE:

Feel free to share it/use it for your own projects!
