User Guide
Use this calculator to determine the voltage in microvolt, millivolt, volt or kilovolt units in a direct current (DC) electrical circuit with a specified current and resistance. Two conversion scales show how the voltage in an electrical circuit changes as current or resistance is changed independently, whilst keeping the other constant.
Formula
The formula used by this calculator to determine the voltage in a DC electrical circuit from the current and resistance is:
V = I · R
Symbols
- V = Voltage (DC)
- I = Current (DC)
- R = Electrical resistance (DC)
Current (I)
This is the electrical current flowing through the DC electrical circuit.
Resistance (R)
This is the electrical resistance of the DC electrical circuit
Voltage (V)
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.
