Practice Problems 1. A load draws 20 kW at a power factor of .8 lagging. The voltage across the load is 220 Vms. The load is connected to an ac source through a line with impedance .09 +j.3 2. Find S, P and Q for the load, the line and the source. Show that all three forms of power (P, Q, S) are conserved. [20+j15 kVA, 1.16+j3.87 kVA, 21.16+j18.87 kVA]
