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.
  • Mechanical energy to electrical energy.

Answer

Correct option: D.
Mechanical energy to electrical energy.

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.
