A load consisting of a 480 ohm resistor in parallel with a (5/9) uF capacitor is connected across the terminals of a sinusoidal voltage source, vg, where vg=240cos5000t V.
a) What is the peak value of the instantaneous power delivered by the source?
b) What is the peak value of the instantaneous power absorbed by the source?
c) What is the average power delivered to the load?
d) What is the reactive power delivered to the load?
e) Does the load absorb or generate magnetizing vars?
f) What is the power factor of the load?
g) What is the reactive factor of the load?
