Resistor Calculator

Find the value of resistors, either by colors or their value, easily and quickly, with visual aid, for students, amateur educators and component sellers.

- For 4-band resistors (functionality for precision resistors will be added soon)

- With a single button switch between "colors" or "value" mode

- The "value" mode is intuitive and corrects you to the existing values ​​of resistors.

- You can choose between Ω, KΩ or MΩ scales

- With little interaction you know the value of that resistance you are looking for.

- For resistances from 0.01Ω to 99,000,000 Ω
