Which of the following correctly describes the energy changes in the generation of light by a hydroelectric power station?
Answer Details
The correct option that describes the energy changes in the generation of light by a hydroelectric power station is:
"Potential energy → mechanical energy → electrical energy → light."
This is because a hydroelectric power station converts the potential energy of water stored at a certain height into mechanical energy by allowing the water to flow down through turbines. The turbines are connected to generators that convert the mechanical energy into electrical energy. Finally, the electrical energy is used to power light bulbs and other electrical devices, producing light.
