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.

Question
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.
