Question

What is hydroelectricity? Explain the basic principle of generation of hydroelectricity with the help of a labelled diagram. 

Answer 1

 Hydroelectricity is the product of a process by which mechanical energy from the flow of water is used to generate electricity.
It works on the principle of conversion of mechanical energy into electrical energy. Mechanical energy from the flow of water is used to rotate turbines, which are connected to a dynamo that generates electricity.
