Question
The figure shows a single-phase power system with three loads. The source voltage is V = 240 20° V
and the impedances of these three loads are: Z1 = 10 230° Q ; Z2 = 10 245° Q ; Z3 = 10 2-90° Q
%3D
Analytically 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 powers supplied by the source.
b) How much real, reactive, and apparent power is being consumed by each load with the
breaker open?
c) Assume that the switch shown in the figure is closed and calculate the current I, the power
factor, the real, reactive and apparent powers supplied by the source.
d) How much real, reactive, and apparent power is consumed by each load with the breaker
closed?
e) What happens to the current emanating from the source when the switch is closed? Why?
V
