At a particular power station, the following energy change takes place:
Potential energy -> Kinetic energy -> Mechanical energy -> Electrical energy
What type of power station it is?
Hydroelectric power station
In a hydroelectric power station, water stored at a height is allowed to flow down through a penstock pipe, which converts the potential energy of the stored water into kinetic energy of the flowing water. The energy of the flowing water is used to rotate the turbine, which is the conversion of kinetic energy into mechanical energy. The rotating turbine generates electricity, which is the conversion of mechanical energy into electrical energy.
The energy change taking place here is:
Potential energy -> Kinetic energy -> Mechanical energy -> Electrical energy
