Find the per-phase impedance of the load, Electrical Engineering

Q. A three-phase, three-wire 208-V system is connected to a balanced three-phase load. The line currents ¯ IA, ¯ IB, and ¯ IC are given to be in phase with the line-to-line voltages ¯VBC, ¯VCA, and ¯VAB, respectively. If the line current is measured to be 10 A, find the per-phase impedance of the load.

(a) If the load is wye-connected.

(b) If the load is delta-connected.
