Single correct option
An electric generator converts
- A. mechanical energy into electrical energy
- B. electrical energy into mechanical energy
- C. chemical energy into electrical energy
- D. electrical energy into heat only
Show answer and solution
Answer: (A) mechanical energy into electrical energy
A generator rotates a coil in a magnetic field, and the changing flux induces an emf (electromagnetic induction). It is the reverse of an electric motor, which converts electrical energy to mechanical energy. Chemical to electrical conversion describes a cell or battery.
