DC watts to volts formula: V(V) = P(W) / I(A)
AC single phase watts to volts formula: V(V) = P(W) / (PF × I(A) )
AC single phase watts to volts with line to line voltage: VL-L(V) = P(W) / (√3 × PF × I(A) ) ≈ P(W) / (1.732 × PF × I(A) )
AC three phase watts to volts with line to neutral voltage: VL-N(V) = P(W) / (3 × PF × I(A) )
