Question

How is electricity produced in a hydroelectric power station?

Answer 1

1. Water in any water body like a river, stream, and other forms can be used to generate electric current.
2. Energy available in moving water depends on the volume and the elevation of the water body.
3. The higher the elevation and greater the flow, the more the electricity is generated.
4. Water when flows through the pipe, known as a pen-stock, spins the blades in the turbine, which spins the generator axle and ultimately generates electricity.

Hence, electricity is produced using water released from reservoir flow.
