Question

What is the sequence of energy transformations associated with a hydroelectric dam?

Answer 1

The sequence of energy transformations associated with a hydroelectric dam is: B) gravitational potential energy into kinetic energy into mechanical energy into electrical energy

Answer 2

Explanation :

A hydroelectric dam is used to produce electricity. The transformation of energy that is associated with a hydroelectric dam is :

Since the water is falling from a height so at that point the potential energy of water converts into kinetic energy. The turbine attached is used to convert the energy in the water to mechanical energy.

Finally, the mechanical energy is converted to electrical energy with the help of a generator.    

Hence, the correct option is (B) " gravitational potential energy into kinetic energy into mechanical energy into electrical energy ".
