The electrical device used for converting mechanical energy into electrical energy is called
general-sciencephysics-light-electricity
- Avoltmeter
- Bammeter
- Cmotor
- Dgenerator
Explanation
A generator converts mechanical energy into electrical energy by electromagnetic induction — rotating a coil in a magnetic field induces an emf (Faraday's law). An electric motor (option C) does the reverse, converting electrical energy into mechanical energy. A voltmeter (option A) measures voltage and an ammeter (option B) measures current; neither converts energy forms. Hence option D.
