How to Calculate Watts to Amps?

DC = Direct Current
DC (W) to (A) calculation

Formula I(A) = P(W)
V(V)

Current I in amps (A) equals to P in watts (W), divided by voltage V in volts.

AC = Alternating Current
AC single phase (W) to (A) calculation

Formula I(A) = P(W)
(PF x V(V))

AC three phase (W) to (A) calculation
Line to line voltage

Formula I(A) = P(W)
(3 × PF × VL-L(V) )

Line to neutral voltage

Formula I(A) = P(W)
(3 × PF × VL-N(V) )

power factor of resistive impedance load is equal to 1
