Question

Figure 12-18  A delta-connected alternator is connected to a wye-connected resistive load. The alternator produces a line voltage of 240 V and the resistors have a value of 6 ohms each. Find the specified values:
-EP(Load) = ____ V.

B) 138.57 
C) 142.47 
D) 145.89

Quizplus · Accepted Answer

To find the EP(load), we need to use the formula EP(load) = VL/√3, where VL is the line voltage of the alternator. In this case, VL = 240 V.

Next, we need to find the phase voltage (VP) of the resistive load by using the formula VP = VL/√3.

VP = 240/√3 = 138.57 V

Finally, to find the EP(load), we can use the formula EP(load) = VP.

EP(load) = 138.57 V

Therefore, the correct answer is choice B.
