An unbalanced wye load consists of a 4 + j3 Ohm impedance connected to phase A, a 3 + j3 Ohm impedance connected to phase B, and a 4 + j5 Ohm impedance connected to phase C. The sequence is ABC with VAB = 208 volt at an angle of 0°. Assuming all currents are flowing from the source to the load, calculate the value of the followings in Polar values:
a. I(A) [where I(A) is the phase A current].
b. I(B) [where I(B) is the phase B current].
c. I(C) [where I(C) is the phase C current].
d. I(N) [where I(N) is the phase N current].

Great Thanks,
