Resistor Color Code Calculator
Calculate resistor values quickly and accurately with our free online tool.
How to Use the Calculator
- Select the number of bands on your resistor (4, 5, or 6).
- Choose the color for each band from the dropdown menus.
- The resistance value, tolerance, and (for 6-band resistors) the temperature coefficient will be calculated and displayed automatically.
