A balanced three-phase source supplies power to three loads. The loads are
Load 1: 30 kVA at 0.8 pf lagging
Load 2: 24 kW at 0.6 pf leading
Load 3: unknown
The line voltage at the load and line current at the source are 208 V rms and 166.8 A rms, respectively. If the combined power factor at the load is unity, find the unknown load.
