Question#5
Figure below shows a simple single-phase AC power system with three loads. The voltage
source is V = 240 < o°v and the impedances of these three loads are
z, = 10 < 30°n
Z2 = 10 < 45°0
Z3 = 10 < -90°n
V
Z,
Answer the following questions about this power system.
a. Assume that the switch shown in the figure is initially open, and calculate the current
I, the power factor, and the real, reactive, and apparent power being supplied by the
source.
b. How much real, reactive, and apparent power is being consumed by each load with
the switch open?
