MCQ

In a hydro power plant:

✓
Potential energy possessed by stored water is converted into electricity.
B
Kinetic energy possessed by stored water is converted into potential energy.
C
Water is heated to produce electricity.
D
Water is converted into steam to produce electricity.

✓

Answer

Correct option: A.

Potential energy possessed by stored water is converted into electricity.

Hydro power plant uses the potential energy stored in water. When water flows down the dam, potential energy is converted into kinetic energy which is used to rotate the turbine which produce electricity.
