A balanced Y-connected load having an impedance of is connected in parallel with a balanced -connected load having an impedance of The paralleled loads are fed from a line having an impedance of The magnitude of the line-to-line voltage of the -load is .

a) Calculate the magnitude of the phase current in the Y-connected load.

b) Calculate the magnitude of the phase current in the -connected load.

c) Calculate the magnitude of the current in the line feeding the loads.

d) Calculate the magnitude of the line voltage at the sending end of the line.
