Question

In a hydroelectric dam the potential energy of water directly changes to:

• A. electric energy only
• B. kinetic energy only
• C. first kinetic energy and then electric energy
• D. first electric energy and then kinetic energy

Answer 1

The correct option is C

first kinetic energy and then electric energy

1. The potential energy is converted into kinetic energy as water flows downhill.
2. The water can be used to turn the blades of a turbine to generate electricity, which is distributed to the power plant's.
3. Potential energy$\to$kinetic energy$\to$electric energy

Hence, the correct answer is option (C).
