A wye-connected alternator that has phase voltages of 277 V is feeding two loads. The first load is wye-connected inductors that have 40 Ω of XL. The second load is delta-connected capacitors that have XC of 60 Ω. How much is the alternator phase current?
A) 6.93 A
B) 14.93 A
C) 24.62 A
D) 28 A

Question

Quizplus · Accepted Answer

The phase current for the wye-connected inductors is calculated using Ohm's law: I = V / XL = 277 V / 40 Ω = 6.93 A. The delta-connected capacitors do not affect the phase current calculation for the wye-connected alternator.
