## User Guide

Use this calculator to determine the current in microamp, milliamp or ampere units, generated by a direct current (DC) electrical circuit for a specified power and voltage. Two conversion scales show how the current will vary when the power or voltage is changed independently.

### Formula

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

I = P / V

#### Symbols

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

### Power (P)

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

### Voltage (V)

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

### Current (I)

This is the electrical current that will flow through the DC electrical circuit with the specified power and voltage.
