प्रश्न
Give scientific reasons.
The construction of turbine is different for different types of power plants.

उत्तर
- Generators produce electricity on the principle of electromagnetic induction and therefore require continuous rotation.
- This rotation is provided by turbines. Different power plants use different energy sources, such as steam, flowing water, wind, or gas, to rotate the turbines.
- Since the nature, pressure, speed, and flow of these energy sources are different, the turbines must be specially designed to operate efficiently with each source.
