## How to Convert Amps to Volts

Voltage is the potential difference in an electrical circuit, measured in volts. It might be easier to think of it as the amount of force or pressure pushing electrons through a conductor. To convert amps to volts we can use a simple formula defined by Watt’s Law.

Per Watt’s Law, voltage is equal to power divided by current.

Voltage_{(V)} = Power_{(W)} ÷ Current_{(A)}

**For example,**let’s find the voltage of a device that uses 120 watts of power with a current of 10 amps.

voltage = watts ÷ amps

voltage = 120 W ÷ 10 A

voltage = 12 V

## Convert Amps to Volts using Resistance

It is also possible to convert amps to volts if resistance is know, thanks to an Ohm’s Law formula. Using Ohm’s Law, we can state that voltage is equal to electrical current times the resistance.

Voltage_{(V)} = Current_{(A)} × Resistance_{(Ω)}

**For example,**let’s find the voltage of a circuit with 1.2 amps of current and 20 ohms of resistance.

voltage = amps × ohms

voltage = 1.2 A ÷ 20 Ω

voltage = 24 V
