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) Compare the results of Problem 4.2.5(a) with those obtained in Problem 4.2.4(a), and explain why they are the same.
(c) Sketch the phasor diagram showing all voltages and currents, with V¯ AB as the reference.

Problem 4.2.5(a)

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

Problem 4.2.4(a)

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