A 117 V(rms), 60Hz household circuit has two 75 Watt lights,PF=1, and a fan using 500VA at 0.78 PF (lagging).
A) Draw the circuit, representing each load by its impedance. Include the switches for each load.
B) Determine the total current required for all loads operating simultaneously.
C) What capacitor in parallel with the loads will give unitypower factor?
