If the current and voltage of a Y-connected load are Vab = 480∠30∘V, Ic = 10∠90∘ A, compute for following:

a) All phase voltages Van, Vbn, Vcn of the load; draw the phasor diagram of the voltages.
b) All phase currents Ia, Ib, Ic of the load; draw the phasor diagram of the currents.
c) The power factor of the load.
d) The real power and reactive power consumed by the load; state whether it is inductive or capacitive.
e) The complex power and apparent power consumed by the load.
