Amps (A) tovolts (V) calculator.

Select calculation type, enter amps and watts or ohms and press the *Calculate* button to get volts:

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

*V*_{(V)} = *P*_{(W)} / *I*_{(A)}

The voltage *V* in volts (V) is equal to the current *I* in amps (A), times the resistance *R* in ohms (Ω):

*V*_{(V)} = *I*_{(A)} × *R*_{(Ω)}
