A.C generator is a device which converts:
Correct answer: B. Mechanical energy into electrical energy
- A. Electrical energy into mechanical energy
- B. Mechanical energy into electrical energy
- C. Chemical energy into mechanical energy
- D. Heat energy into electrical energy
Explanation
An AC generator is a device that converts mechanical energy into electrical energy.AC generators, also known as alternators, operate based on the principle of electromagnetic induction. They convert mechanical energy, typically from a rotating shaft or turbine, into electrical energy. As the coil of wire within the generator rotates in a magnetic field, it induces an alternating current (AC) in the coil.

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.
