Volts to amps calculator

Volts (V) to amps (A) calculator.

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

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

I_(A) = P_(W) / V_(V)

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

I_(A) = V_(V) / R_(Ω)
