Answer & explanation:
Hydroelectric power is obtained in hydroelectric plants, with dams, turbines and various other equipment. These dams are built on river beds, which have their flow contained generating a large reservoir of water.
In short, hydroeletric power is generated by capturing mechanical energy from the movement of the turbines.
The turbines installed in the dams of the hydroelectric plant have a certain height difference. In this way, water falls hard on the turbines, which are then moved, transforming the potential energy into mechanical energy.
This mechanical energy is captured by an electricity generator and, finally, transformed into electrical energy.
