Question

A generator transforms

a. potential energy into kinetic energy.
b. mechanical energy into electrical energy.
c. magnetic energy into electrical energy.
d. friction into electrical energy.

Answer 1

it is B ! generator changes mechanical energy into electrical energy !

Answer 2

b. mechanical energy into electrical energy.

Step-by-step explanation:

A generator is based on the principle of Faraday's law of induction. A conducting coil is rotated in a magnetic field. This induces emf in the coil and current is generated. Thus, a generator transforms mechanical energy into electrical energy. Work done to rotate the axle is converted to electrical energy. A generator is used in electrical power grids.
