Question: Three loads are connected in parallel to a 1200 V rms source. Load 1 absorbs 60 kVAR at pf = 0.85 lagging, load 2 absorbs

Three loads are connected in parallel to a 120∠0° 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 impedance.
(b) Calculate the power factor of the parallel combination.
(c) Determine the current supplied by the source.
