## Amps to Volts conversion

How to convert electric current in amps (A) to voltage in volts (V)

### Amps to volts conversion with watts

The voltage *V*, in volts (V) across a circuit is calculated by dividing the power *P *by the Current *I *through the circuit, in amps (A).

V(V) = P(W) / I(A)

Therefore:

Volt = watt / amp or V = W / A

**Example**

Calculate the voltage supply in a system, whereby the current flow is 5 amps and the power consumption is 50 watts.

*Solution*

V = *P* / *I*

*V* = 50W / 5A = 10V

### Converting current *I* (A) to Voltage (V) using the Resistance in ohms (Ω)

To calculate voltage in volts (V), in this case, you should multiply the resistance, in ohms (Ω) by the current *I* in AMPS (A).

*V*_{(V)} = *I*_{(A)} × *R*_{(Ω)} so volt = amp × ohm

Or

V = A × Ω

**Example**

Calculate the voltage across a circuit where the current through the circuit is 4A and the resistance is 10Ω

*Solution*

Voltage V = Current *I* × resistance Ω, according to Ohm’s law.

*V* = 4A × 10Ω = 40V
