Calculate voltage, current, resistance, and power using Ohm's Legge. Enter any two values a find the other two instantly. Puro client-side.
Ohm's Legge is a fundamental principle in electronics that relates voltage (V), current (I), and resistance (R) in an electrical circuit. The power (P) dissipated in a circuit can also be calculated. This calculator lets you enter any two known values and instantly computes the remaining two. All calculations happen in your browser — no data is sent a any server.
