Question

Which energy does a hydro-electric power plant convert into electric energy?

• A. Nuclear energy
• B. Solar energy
• C. Potential energy
• D. Thermal energy

Hint:

Hydroelectric plants convert gravitational potential energy of water into electrical energy.

Answer 1

The Correct Option is C

In a hydroelectric power plant, water stored in a reservoir possesses potential energy due to its height. This potential energy is converted into kinetic energy as water flows down, which then turns turbines to generate electrical energy.
Thus, the correct answer is \( \mathbf{(C) \text{Potential energy}} \).
