ALTERNATING CURRENT(AC):
CURRENT(single phase):
I = P/(Vp cos(pf))
VOLTAGE(single phase):
V=P/(Vp cos(pf))
POWER:
V*I cos(pf)

Il = line current(amps.),
Ip = phase current(amps.),
Vp = phase voltage(volts),
Vl = line voltage(volts)
Z = impedance(ohms),
P = power(watts),
pf = power factor(angle),
VA = volt ampers
