User Guide

Use this calculator to determine the voltage in microvolt, millivolt or volt units, applied to a direct current (DC) electrical circuit with a specified power and current. Two conversion scales show how the voltage will vary  when the power or current is changed independently.

Formula

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

V = P / I

Symbols

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

Power (P)

This is the electrical power generated in a DC electrical circuit.

Current (I)

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

Voltage (V)

This is the DC voltage or electrical potential difference that would be applied to or generated by an electrical circuit with the specified power and current values.
