Question

When a hydroelectric dam is operating, falling water moves turbines, which are able to generate an electric current. Which energy transformations are taking place during operation?(1 point)

A. kinetic to potential to electrical

B. potential to kinetic to chemical

C. kinetic to electrical to potential

D. potential to kinetic to electrical

Answer 1

The correct answer is:

D. potential to kinetic to electrical

In a hydroelectric dam, water stored at a height has potential energy. When it is released, this potential energy is converted to kinetic energy as the water falls. The falling water then moves the turbines, which transforms that kinetic energy into electrical energy.
