MCQ
An AC generator is a device which converts:
  • A
    Electrical energy to mechanical energy.
  • B
    Heat energy to electrical energy.
  • C
    Heat energy to light energy.
  • D
    Mechanical energy to electrical energy.
✓

Answer

  1. Mechanical energy to electrical energy.

Explanation:

An AC generator converts mechanical energy into electrical energy, while a motor does the opposite - it converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field.
