A two terminal electrical component which reduces electric current are resistors. Color codes are used to indicate values. A 4 (four) band color code resistor has 4 (four) bands, 1 st indicating the first significant digit, 2nd band indicating the second digit, 3rd multiplier and 4th tolerance. This calculator is used to find the resistance and tolerance value based on the color codes.

The electrical function of a resistor is identified by resistance and is implemented within IC's
