In the dams water is stored in the high reservoirs and then made to fall down. This falling water then rotates the turbines to generate electricity. In this energy conversion process can you tell the initial and final energies respectively?

1. Kinetic energy and electrical energy
2. Potential energy and kinetic energy
3. Potential energy and electrical energy
4. Kinetic energy and potential energy

 In this energy conversion process, the kinetic energy of the falling water on the turbine gets converted into electrical energy.

Therefore, option a). is correct.
