Question:

A balanced delta-connected load is supplied by a 60-Hz three-phase source with a line voltage of 240 V. Each load phase draws 6 kW at a lagging power factor of 0.8. Find:
(a) The load impedance per phase
(b) The line current
(c) The value of capacitance needed to be connected in parallel with each load phase to minimize the current from the source
