Chapter 11, Problem 55E
A load is drawing 10 A rms when connected to a 1200 V rms supply running at 50 Hz. If the source is operating at a lagging PF of 0.9, calculate (a) the peak voltage magnitude; (b) the instantaneous power absorbed by the load at t = 1 ms; (c) the apparent power supplied by the source; (d) the reactive power supplied to the load; (e) the load impedance; and (f) the complex power supplied by the source (in polar form).
