Q. (a) A balanced wye-connected load with per-phase impedance of 20 + j10 is connected to a balanced 415-V, three-phase supply through three conductors, each of which has a series impedance of 2 + j4 . Find the line current, the voltage across the load, the power delivered to the load, and the power lost in the line conductors.
(b) Repeat the problem if the three per-phase load impedances of part (a) were connected in delta.
