Question

What energy conversion takes place in hydro power plants?

• A. Potential energy $\to$ Kinetic energy $\to$ Electrical energy
• B. Kinetic energy $\to$ Potential energy $\to$ Electrical energy
• C. Potential energy $\to$ Chemical energy $\to$ Electrical energy
• D. Thermal energy$\to$ Kinetic energy $\to$ Electrical energy

Answer 1

The correct option is A Potential energy $\to$ Kinetic energy $\to$ Electrical energy

In hydro power plants, the potential energy of the water which is stored in dams is converted to kinetic energy by making them flow. Then the water is used to rotate turbines, where they generate electrical energy.

So the correct energy conversion is:
Potential energy $\to$ Kinetic energy $\to$ Electrical energy
