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
