PHY 102 Electromagnetic Induction Objective Question
Take CBT

Question

In a DC generator, the output voltage is not constant but:
Options
A Sinusoidal
B Pulsating (fluctuates in magnitude but has constant polarity)
Correct Answer
C Constant DC
D Zero
Correct Answer

Option B is the correct answer.

Detailed Explanation

A DC generator produces pulsating DC: the voltage magnitude varies with the rotation angle, but the commutator maintains the same polarity (direction).

Hint

Unidirectional but not constant.
