Resistor Colour Code calculator

Welcome to Resistor Colour Code calculator

Our online resistor colour code calculator is quite straightforward. Here's a general guide on how to use one this application:

1. Select Resistor number band: Select desired band between 3-band, 4-band and 5-band.
2. Input Resistor Colour band: Select dropdown menus where you can select the colours of the bands on your resistor. The number of bands may vary, but most resistors have either three, four or five bands. Enter the colours of each band from left to right. Each colour represents a specific digit or value.
3. Check Tolerance Band (Optional): If your resistor has a tolerance band (usually the last band), select its colour as well. The tolerance band indicates how much the resistor's actual value can deviate from its nominal value.
4. Click Calculate: Once you've entered all the colours, the calculator will display the resistance value of the resistor based on the colours you provided and tolerance. This value is shown in ohms (Ω)
5. Legend for displayed Values:
   • K - Kiloohms (1,000 ohms)
   • M - Megaohms (1,000,000 ohms)
   • G - Gigaohms (1,000,000,000 ohms)

By following these steps, you should be able to effectively use our online resistor colour code calculator to determine the resistance value of a resistor. Enjoy!
