Problem 8. A balanced three-phase source furnishes power to the following three loads: Load 1: 1 kVA at 0.83 pf lagging Load 2: unknown Load 3: 8 kW at 0.7071 pf leading If the line current is 84.6 A (rms), the line voltage at the load is 208 V (rms), the combined load has a 0.8 pf lagging, determine the unknown load. Assume that the line impedance is zero.
