Question

Which transformation of energy occurs in a hydroelectric power plant? A. Potential to chemical energy B. Chemical to potential energy C. Chemical energy to kinetic energy D. Kinetic to electrical E. Electrical to potential energy

Answer 1

The correct answer to the question is D). Kinetic to electrical.

EXPLANATION:

Hydro electric power plants are the electricity generation plants which capture the energy of falling water to produce current.

The water present at the top of a dam has potential energy. When the water is allowed to fall from certain height, the potential energy of the water is converted into kinetic energy.

The falling water moving with high speed is allowed to fall on a turbine. The kinetic energy of the water will rotate the turbine. The turbine is attached to a generator which will produce electricity due to the electromagnetic induction.

Hence, we see that the kinetic energy of the water is converted into electric energy.

Answer 2

D. kinetic energy to electrical energy
