An AC source of 140V feeds 33A to a load, though a cable represented by an unknown resistance R in series with an unknown inductive reactance X. The manufacturer of that cable says, in the catalog, that X=5R. The voltage at the load is 115V. The power supplied by the source is measured as 3kW. What are the active and reactive power at the load? What percentage of the active power delivered by the source is lost as feeder heat losses? This is what I have done so far http://answerboard.cramster.com/Answer-Board/Image/200711832026333008880273800009062.jpg Is is parallel to Vr ; angle btwn Vr and Vx = 90 degrees VL indicates V load, Vs = V source, Vr = V resistor, Vx = V inductor The prof gave us a hint saying that "nothing stops you from extending the lines" but I stilll cant get all the angles and lengths. Someone please help. I really need to know how to solve this question.
