Question

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

Faraday's law of electromagnetic induction states that the magnitude of the induced electromotive force (e.m.f) in a circuit is directly proportional to the rate of change of magnetic flux linkage through the circuit (ε = -N dΦ/dt).

Hint

Recall Faraday's Law of Induction, which describes how a changing magnetic field creates an e.m.f.
