## User Guide

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.

### Formula

The formula used by this calculator to determine the DC electrical power generated from the voltage and current is:

P = V · I

#### Symbols

- P = Electrical power (DC)
- V = Voltage (DC)
- I = Current (DC)

### Voltage (V)

This is the DC voltage or electrical potential difference applied to or generated by the electrical circuit.

### Current (I)

This is the electrical current flowing through the DC electrical circuit.

### Power (P)

This is the resulting electrical power generated by a DC electrical circuit with the entered values for voltage and current .
