Use this calculator to determine the power in watts, kilowatt, megawatt, volt-ampere, kilovolt-ampere or electrical horsepower units generated by a direct current (DC) electrical circuit for a specified voltage and current. Two conversion scales show how the power will vary when the voltage or current is changed independently.
The formula used by this calculator to determine the DC electrical power generated from the voltage and current is:
P = V · I
- P = Electrical power (DC)
- V = Voltage (DC)
- I = Current (DC)
This is the DC voltage or electrical potential difference applied to or generated by the electrical circuit.
This is the electrical current flowing through the DC electrical circuit.
This is the resulting electrical power generated by a DC electrical circuit with the entered values for voltage and current .
