A single-phase source delivers 100 kW to a load operating at 0.8 lagging power factor. In order to improve the system's efficiency, power factor improvement (correction) is achieved through connecting a capacitor in parallel with the load. Calculate the reactive power to be delivered by the capacitor (considered ideal) in order to raise the source power factor to 0.95 lagging, and draw the power triangles. Also find the value of the capacitance, if the source voltage and frequency are 100 V (rms) and 60 Hz, respectively. Assume the source voltage to be a constant and neglect the source impedance as well as the line impedance between source and load.
