Three loads are connected in parallel to a 120<0degrees V rms source. Load 1 absorbs 60 kVAR at pf=0.85 lagging, load 2 absorbs 90 kW and 50 kVAR leading, and load 3 absorbs 100 kW at pf=1. (a) Find the equivalent inpedance. (b) Calculate the power factor of the parallel combination. (c) Determine the current supplied by the source.
