A device that converts mechanical energy into electrical energy is called:
Correct answer: A. A.C generator
- A. A.C generator
- B. Motor
- C. Converter
- D. Vibrator
Explanation
A device that converts mechanical energy into electrical energy is called an A.C. generator.An AC generator, also known as an alternator, operates by converting mechanical energy into electrical energy. This conversion is achieved through the principle of electromagnetic induction, where a rotating coil of wire within a magnetic field 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.
