364 14.27 Three loads are connected in parallel across a voltage source of 208 V rms: Load 1: An impedance of 15+ j8 Q. Load 2: A motor draws 22 kW at 0.8 pf lagging. Load 3: A capacitive load rated at 16 kVA at 0.85. Determine the total complex power, the power factor of the combined load, and the necessary capacitance to correct the power factor of the combined load to unity pf.
