Resistor Calculator

Resistors are electronic components used extensively on the circuit boards of electronic equipment. They are color coded with stripes to reveal their resistance value (in ohms) as well as their manufacturing tolerance. Should you encounter a resistor and don't know the color codes, use this page to determine its resistance value.
