Hydroelectricity Power:

Hydroelectricity power is a renewable source of energy that generates electricity from the gravitational force of falling or flowing water. The process of hydroelectricity power involves converting potential energy of water into kinetic energy which in turn is converted into electrical energy.

Answer:

The correct answer is option 'B' - Potential energy is transferred to kinetic.

Explanation:

Hydroelectricity power is generated by the conversion of potential energy into kinetic energy. The potential energy of water is stored in reservoirs, dams or other water bodies. When water is released from these reservoirs, it falls down due to gravity and gains kinetic energy. This kinetic energy is used to rotate turbines which in turn generate electrical energy.

The process of hydroelectricity power can be explained in the following steps:

1. Potential Energy: Water is stored in reservoirs, dams or other water bodies. This water has potential energy which is stored as a result of the height of the water above the turbine.

2. Release of Water: The water is released from the reservoir or dam and falls down due to gravity. This falling water gains kinetic energy.

3. Turbines: The kinetic energy of the falling water is used to rotate turbines. The turbines are connected to generators which convert the kinetic energy into electrical energy.

4. Electrical Energy: The electrical energy generated by the turbines is transmitted through power lines to homes, industries, and other places where electricity is needed.

Conclusion:

In conclusion, the correct option for the transfer of energy in hydroelectricity power is option 'B' - Potential energy is transferred to kinetic. Hydroelectricity power is a renewable source of energy that is generated by converting the potential energy of water into kinetic energy which is then converted into electrical energy.

Hydroelectricity power stations use the kinetic energy in moving water. But the water comes from behind a dam built across a river valley. The water high up behind the dam contains potential energy.##@
