Question

In a hydropower plant

• A. Potential energy possessed by stored water is converted into electricity
• B. Kinetic energy possessed by stored water is converted into potential energy
• C. Electricity is extracted from water
• D. Water is converted into steam to produce electricity

Answer 1

The correct option is A

Potential energy possessed by stored water is converted into electricity

Hydro-electric power plants:

1. Hydroelectric power plants use the flow of water to generate electricity, which is referred to as hydro energy.
2. Gravitational potential energy due to falling water is converted into kinetic energy which is used by the hydroelectric power plant.

Working on a hydroelectric power plant:

1. As the reservoir's water falls to a lower level, the potential energy trapped in the water will be released as kinetic energy.
2. Water from the reservoir will be forced to fall on the turbine, causing the turbine to rotate owing to the force of the waterfall.
3. After connecting the turbine to the generator, the generator will create electricity. The generated electricity is sometimes referred to as hydroelectric current or hydropower.

Therefore, in a hydropower plant, potential energy possessed by stored water is converted into electricity.

Hence, option A is the correct answer.
