Option a is correct. Because, in order to produce electricity, high-rise dams are constructed on the river to obstruct the flow of water in large reservoirs. The water level increases or rises and in this process, the kinetic energy of flow water gets converted into potential energy. The water from the high level in the dam is carried through pipes, to the turbine, at the bottom of the dam. As the turbine is connected to the generator, turbine starts to rotate faster as the flowing of water increases. How much faster the turbine starts to rotate, that much electricity will be obtain to us.

Initial Energy:
The initial energy in this energy conversion process is kinetic energy. Kinetic energy is the energy possessed by an object due to its motion. In the case of a dam, the water stored in the high reservoirs has gravitational potential energy due to its elevated position. As the water falls down, this potential energy is converted into kinetic energy.
Final Energy:
The final energy in this energy conversion process is electrical energy. Electrical energy is the energy carried by electric charges and is used to power various electrical devices. In a dam, the falling water rotates the turbines, which are connected to generators. The rotation of the turbines converts the kinetic energy of the falling water into mechanical energy. This mechanical energy is then further converted into electrical energy by the generators.
Energy Conversion Process:
The energy conversion process in a dam can be summarized as follows:
1. Potential Energy to Kinetic Energy:
- The water stored in the high reservoirs has gravitational potential energy due to its elevated position.
- When the gates of the dam are opened, the water falls down from the high reservoirs to the lower reservoirs.
- As the water falls, its potential energy is converted into kinetic energy. The falling water gains speed and momentum, possessing kinetic energy.
2. Kinetic Energy to Mechanical Energy:
- The falling water is directed towards the turbines, which are located at the bottom of the dam.
- The force of the falling water causes the turbines to rotate.
- The kinetic energy of the falling water is transferred to the turbines, resulting in the generation of mechanical energy.
3. Mechanical Energy to Electrical Energy:
- The rotating turbines are connected to generators.
- As the turbines spin, they transfer their mechanical energy to the generators.
- The generators convert this mechanical energy into electrical energy, which can be used to power homes, businesses, and industries.
Conclusion:
In the energy conversion process in a dam, the initial energy is the potential energy of the water stored in the high reservoirs, which is converted into kinetic energy as the water falls. The final energy is the electrical energy generated by the rotating turbines and generators.
