Amps to Volts calculator

Amps to volts calculation with watts

Enter the power in watts (W), current in amps (A), then press the Calculate button to get the result in volts (V).

V_(V) = P_(W) / I_(A)

The voltage V in volts (V) is equal to the power P in watts (W), divided by the phase current I in amps (A).

Amps to volts calculation with ohms

Enter the current in amps (A), resistance in ohms (Ω), then press the Calculate button to get the result in volts (V).

V_(V) = I_(A) × R_(Ω)

The voltage V in volts (V) is equal to the phase current I in amps (A), multiplied by the resistance R in ohms (Ω).
