The **Voltage** calculator computes the Voltage (V) based on Ohm's Law using Power (P) and Current (I).

**INSTRUCTIONS:** Choose units and enter the following:

- (
**P**) This is the electrical power. - (
**I**) This is the electrical current.

**Voltage (V):** The calculator returns the potential in volts. However, this can be automatically converted to other electric potential units via the pull-down menu.

### General Information

For more information on the relationship between electrical power, current, resistance and potential, see the Ohm's Law Calculator.

#### Ohms Law Calculators

**Power (P) = I • V****Power (P) = R • I²****Power (P) = V² / R****Volts (V) = I • R****Volts (V) = P / I****Volts(V) = √(P • R)****Resistance (R) = V²/P****Resistance (R) = P / I²****Resistance (R) = V / I****Current (I) = V / R****Current (I) = P / V****Current (I) = √(P/R)**
