Electrical Power Calculator

Calculate electrical power, current, or voltage.

P = I × V

Enter any 2 values to calculate the remaining

Power (P) (Watts)

Current (I) (Amperes)

Voltage (V) (Volts)

Enter values above to calculate

How to Use

This calculator uses the formula P = I × V.

Enter any 2 of the 3 values and the calculator will solve for the missing variable automatically.
