- Power & current to voltage (DC)
- Current & resistance to voltage (DC)
- Power & resistance to current (DC)
Use this calculator to determine the voltage in microvolt, millivolt, volt or kilovolt units, generated by a direct current (DC) electrical circuit for a specified power and resistance. Two conversion scales show how the voltage will vary when the power or resistance is changed independently, whilst the other remains fixed with the entered value.
The formula used by this calculator to determine the DC voltage from the power and resistance of the circuit is:
V = √ (P · R)
- V = Voltage (DC)
- P = Electrical power (DC)
- R = Resistance (DC)
This is the electrical power generated in a DC electrical circuit.
This is the electrical resistance of the DC electrical circuit
This is the DC voltage or electrical potential difference applied to or generated by the electrical circuit with the entered values for current and resistance
