Electrical Tools

Ohm's Law Calculator

Calculate voltage, current, resistance, and power using Ohm's law. Enter any two values to compute the other two instantly. Supports milli/kilo units.

Enter any 2 values

V — Voltage (V)

I — Current (A)

R — Resistance (Ω)

P — Power (W)

V = I × R

P = V × I = I² × R = V² / R
