For a balanced star-connected load, the neutral current is __________.
A) zero
B) one-third of the sum of the three line currents.
C) the sum of the three line currents.
D) 1.732 times any one of the line currents.

Question

Quizplus · Accepted Answer

In a balanced star-connected load, the three phase currents are equal in magnitude but 120 degrees out of phase with each other. When these currents are summed vectorially, they cancel each other out, resulting in a neutral current of zero.

For a Balanced Star-Connected Load, the Neutral Current Is __________
