How do energy transformations occur in a hydroelectric plant? The potential energy of water is converted to mechanical energy by a turbine.

The kinetic energy of water is converted by a dam into potential energy.

The kinetic energy of water is converted by a generator into electric energy.

The potential energy of water is converted by a transformer into electric energy.

The answer is #3: The kinetic energy of water is converted by a generator into electric energy.

Explanation:

Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.
