The induced emf does not depend on:
Correct answer: C. Resistance of the coil
- A. Area of the coil
- B. No. of turns of coil
- C. Resistance of the coil
- D. Length of coil
Explanation
Induced emf does not depend upon the resistance or circuit. It depends upon the time rate of change of magnetic flux. According to Farady's law:

About Electromagnetic Induction
Changing magnetic flux induces an emf according to Faraday's law, while Lenz's law gives the direction that opposes the change producing it. Transformers apply induction between coils to step alternating voltage up or down, with turns ratio, current transformation and energy losses determining practical operation.
