DC watts to volts calculation

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)

AC single phase watts to volts calculation

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

V = P / (PF × I )

AC three phase watts to volts calculation

The voltage V in volts (V) is equal to the power P in watts (W), divided by square root of 3 times the power factor times the current I in amps (A):

V = P / (√3 × PF × I )
