Three equal impedances, 60 + j30 Ω each, are delta-connected to a 230-V rms, three-phase circuit.

Another three equal impedances, 40 +j10 Ωeach, are wye-connected across the same circuit at the same points. Determine:

(a) the line current

(b) the total complex power supplied to the two loads

(c) the power factor of the two loads combined
