Compute the complex power S (in polar form) drawn by a certain load if it is known that (a) it draws 100 Waverage power at a lagging PF of 0.75; (b) it draws a current I = 9 + j5 A rms when connected to the voltage 120/32 V rms; (c) it draws 1000 Waverage power and 10 VAR reactive power at a leading PF; (d) it draws an apparent power of 450 Wat a lagging PF of 0.65.
