In an AC generator the emf will be maximum when factor sinωt is equal to:
Correct answer: C. 1
- A. Zero
- B. 2
- C. 1
- D. 1/2
Explanation
B is the correct option. This option is correct. The emf will be maximum when the value of the sine function is at its maximum. The sine function sin(θ) reaches its maximum value of 1.

About Faraday's Law
Faraday's law states that an induced electromotive force equals the rate of change of magnetic flux linkage through a circuit. Questions cover changing field, area, angle or motion, the negative sign associated with Lenz's law, and the distinction between induced emf and the current that may flow in a closed circuit.
