Chapter 5, Problem 5.81P
Two loads. A and B, are connected in parallel across a 1-kV-rms 60-Hz line, as shown in Figure P5.81. Load A consumes 10 kW with a 90 percent lagging power facto. Load B has an apparent power of 15 ICVA with an 80 percent lagging power factor. Find the power, reactive power, and apparent power delivered by the source. What is the power factor seen by the source?
