Question

The waveform of the emf generated undergoes one complete cycle when?

(a) Conductors move past north pole

(b) Conductors move past south pole

(c) Conductors move past north and south poles

(d) Conductors are stationary

The question was posed to me in quiz.

This intriguing question originated from Relationship between Frequency, Speed and Number of Pole Pairs in section Alternating Voltage and Current of Basic Electrical Engineering

Answer 1

Correct answer is (c) Conductors move past north and south poles

To elaborate: The waveform of the e.m.f. generated in an a.c. generator undergoes one complete cycle of variation when the conductors move past an N and an S pole.
