A source supplies power to the following three loads connected in parallel: (1) a lighting load drawing 10 kW . (2) an induction motor drawing 10 kVA at 0.90 power factor lagging, and (3) a synchronous motor operating at 10 hp , 85 % effIciency and 0.95 power factor leading ( 1 hp = 0 .746 kW ) . Determine the real, reactive, and apparent power delivered by the source. Also, draw the source power triangle.
