Power (P) = Watts (or kW).
Volts (V) = Voltage.

Ohms Law Formula - Single Phase:
To calculate Voltage (V): V = I x R
To calculate Amps (I): I = V ÷ R
To calculate Resistance (R): R = V ÷ I

Simple, fast, and accurate — the electrical calculator you'll reach for every day.

Trusted by the professionals since 2011.
