Balanced delta-connected load, Electrical Engineering

Q. A balanced delta-connected load with a per-phase impedance of 12 + j9 is supplied by a 173-V, 60-Hz three-phase source.

(a) Determine the line current, the power factor, the total volt-amperes, the real power, and the reactive power absorbed by the load.

(b) Sketch the phasor diagram showing all voltages and currents, with ¯V_AB as the reference.
