Three loads are connected in parallel to a 220/0°Vrms ac source. Load 1 absorbs 80kVars at 0.85 pf lagging, load 2 absorbs 90kW and 50kVAR leading and load 3 absorbs 100kW at pf =1. a) Find the equivalent impedance. b) Find the overall power factor. c) Calculate the total real, reactive and apparent power.
