Name the device which converts mechanical energy into electrical energy.

A

DC generator

B

AC generator

C

Transformer

D

Motor

Text Solution

Verified by Experts

The correct Answer is:
A, B

(a,b) : Mechanical energy is needed to rotate the armature of generator inside magnetic field and then due to electromagnetic induction mechanical energy is converted into electric energy . Hence options ( a) and (b) are correct . Motor converts electrical energy into mechanical energy. Transformer is used to change the voltage only.
