Question
i need the answer quickly
11.71 A balanced three-phase source supplies power to three
loads:
Load 1: 18 kVA at 0.8 pf lagging
Load 2: 10 kW at 0.6 pf leading
Load 3: unknown
If the line voltage at the loads is 208 V rms, the line
current at the source is 116.39 A rms, and the combined
power factor at the load is 0.86 lagging, find the
unknown load.
