How is electrical energy produced in dams? (That is, how is the energy of motion of the water converted to AC electricity?)

To determine
How electrical energy produced in dams from energy of moving water.


The principle is conservation of energy. Since the water stored in dam has potential energy, as it falls down the potential energy gets converted into kinetic energy. When the moving water hits the turbine wheel the kinetic energy of the water starts to spin the turbine thus converting the kinetic energy of the moving water to the mechanical energy. Turbine is associated with a rotor consists of coil placed between magnets finally convert the mechanical energy to electrical energy...
