The application is an easy-to-use SMD-code calculator for calculating the resistance of a resistor. The application supports the 3-digits, 4-digits, and EIA-96 coding systems . 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
