A balanced 3-phase 3-wire system has a line voltage of 500Vrms. Two balanced Y-connected sources are present. One is acapacitive load with 7-2j Ω per phase, and the other is aninductive load with 4+2j Ω per phase.
Find:
(a) the phase voltage;
(b) the line current;
(c) the total power drawn by the load;
(d) the power factor at which the source is operating.
