The application is an easy-to-use color code calculator for calculating the resistance of a resistor. The application supports color codes for 3, 4, 5, and 6-band resistors. Resistor A resistor is a component that is used in electrical circuits to limit the current flow. The resistance of a resistor is measured in Ohms (Ω). When a current (I) of one Ampere passes through a resistor with a voltage drop (U) of one Volt, the resistance of a resistor (R) corresponds with one Ohm. This ratio is rep
