Question

The magnitude of induced e.m.f is proportional to
Options
A rate of change of current
B rate of change of voltage
C rate of change of magnetic flux linkage
Correct Answer
D rate of change of resistance
Correct Answer

Option C is the correct answer.

Detailed Explanation

According to Faraday's Law of electromagnetic induction, the magnitude of the induced electromotive force (e.m.f.) in a circuit is directly proportional to the rate at which the magnetic flux linking the circuit changes. Magnetic flux linkage is the product of the number of turns in the coil and the magnetic flux through each turn.

Hint

Recall Faraday's Law of Induction and what quantity's rate of change it relates to induced e.m.f.
