The turbines can be seen inside this hydroelectric dam. Why are they located at that particular height?

Question

There is a small drop, so the water will still have a lot of kinetic energy to transfer to the turbine.

There is a large drop, so the water will have a lot of kinetic energy to transfer to the turbine.

There is a large drop, so the water will have a lot of potential energy to transfer to the turbine.

There is a small drop, so the water will still have a lot of potential energy to transfer to the turbine.

Answer 1

The correct reason for why the turbines are located at a particular height in a hydroelectric dam is:

There is a large drop, so the water will have a lot of potential energy to transfer to the turbine.

In hydroelectric power generation, turbines are positioned at locations where there is significant elevation change (a large drop). This maximizes the potential energy of the water, which is then converted into kinetic energy as it flows down, ultimately being transformed into mechanical energy by the turbines to generate electricity.
