In hydel power station, the motion produced in turbines is due to
-
- flow of water
- burning of coal
- burning of diesel
- production of steam
- flow of water
Correct Option: A
A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work.Hydroelectric power comes from water at work, water in motion. To generate electricity, water must be in motion. This is kinetic (moving) energy. When flowing water turns blades in a turbine, the form is changed to mechanical (machine) energy. The turbine turns the generator rotor which then converts this mechanical energy into another energy form — electricity.
