Question

In a hydroelectric power plant, more electrical power can be generated if waterfalls from a greater height because

• A. its temperature increases
• B. larger amount of potential energy is converted into kinetic energy
• C. the electricity content of water increases with height
• D. more water molecules dissociate into ions

Answer 1

The correct option is B

larger amount of potential energy is converted into kinetic energy

Hydro-electric power plants

1. Hydroelectric power plants use the flow of water to generate electricity, which is referred to as hydro energy.
2. The kinetic energy created by gravitational potential energy due to falling water is used by the hydroelectric power plant.
3. As a result, raising the height of the fall will increase the amount of energy stored, and a big amount of potential energy will be converted into kinetic energy, resulting in the generation of additional electric energy.

Working on a hydroelectric power plant

1. As the reservoir's waterfalls 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.
4. Increasing the height of its fall will increase the quantity of energy stored, and a large amount of potential energy will be converted into kinetic energy, resulting in more electric energy being generated.

Hence, option B is the correct answer.
