DC watts to amps calculation

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)

AC single phase watts to amps calculation

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

I_(A) = P_(W) / (PF × V_(V) )

AC three phase watts to amps calculation

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

I_(A) = P_(W) / (√3 × PF × V_(V) )
