A delta-connected alternator is connected to a wye-connected resistive load. The alternator produces a line voltage of 240V, and the resistors have a value of 6 ohm each. If EL(Load) = 240V, then EP(Load) = ____V.
A) 80
B) 138.57
C) 160
D) 415.68

Question

Quizplus · Accepted Answer

In a wye-connected system, the line voltage (EL) is related to the phase voltage (EP) by the equation EL = √3 * EP. Given that EL(Load) = 240V, solving for EP gives EP = EL / √3 = 240V / √3 ≈ 138.57V.
