A balanced Y-connected load having an impedance of 96-j28 22 per phase is connected in parallel with a balanced A-connected load having an impedance of 144 +j42 2 per phase. The paralleled loads are fed from a line having an impedance of j1.5 Q2 per phase. The RMS value of the line-to-neutral voltage of the Y-connected input is 240V. a) Calculate the magnitude of the current in the line feeding the loads b) Draw the phasor diagram for input three-phase line voltages, and the line currents
