Question

name the type of energy transformations that take place in hydro power plant

Answer 1

The principle behind hydroelectric power is law of conservation of energy. That is energy can neither be created nor be destroyed. i.e., One form of energy is converted to another form.
In hydroelectric power, the fast moving water strikes the turbines and they start moving and this energy is used to run electric generators.
The transference of energy takes place from Kinetic energy to mechanical energy.
