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.
The formula used by this calculator to determine the DC current from the power and voltage of the circuit is:
I = P / V
- I = Current (DC)
- P = Electrical power (DC)
- V = Voltage (DC)
This is the electrical power generated in a DC electrical circuit.
This is the DC voltage or electrical potential difference that is applied to or generated from the electrical circuit.
This is the electrical current that will flow through the DC electrical circuit with the specified power and voltage.
