8)This MCQ QUESTION FROM BASIC POWER ELECTRICAL ENGINEERING course.

Two balanced 3-phase loads are connected in parallel. Load 1 is Y-connected with a phase impedance of (20-j15) ohms. Load 2 is Delta-connected with a phase impedance of (30+j21) ohms. The line voltage magnitude across the loads is 100 V. The complex power of Load 1 is: Select one: O a. 320 W - j 240 VAR b. 106.7 W - j 80 VAR C. None of these answers is correct d. 106.7 W + j 80 VAR e. 320 W + j 240 VAR
