Volts to Amps calculator

Volts to Amps calculation with watts

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

I_(A) = P_(W) / V_(V)

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

Volts to Amps calculation with ohms

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

I_(A) = V_(V) / R_(Ω)

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