In the circuit shown in Figure 4, the load voltage is Vrms 156020°. Notice that Vrms = | Vrms | = 1560 and ZVrms = 0°. The apparent power on the load is 33 kVA at a lagging power factor of 0.71. f= 60 Hz. (a) Find the average power PL, reactive power QL, and the complex power SL of the load without C. (b) Find the impedance ZL of the load without C. (c) Find the resistance R and inductance L of the load without C. (d) Find the value of the capacitance C to raise the power factor to 0.991 (lagging).
