Figure P1-14 shows a simple single-phase ac power system with three loads. The impedances of these three loads are

Z1 = 5<30°Ω

Z2 = 5<45° Ω

Z3 = 5< - 90°Ω

Answer the following questions about this power system.

(a) Assume that the switch shown in the figure is open, and calculate the current I, the power factor, and the real, reactive, and apparent power being supplied by the source.

(b) Assume that the switch shown in the figure is closed, and calculate the current I, the power factor, and the real, reactive, and apparent power being supplied by the source.
