उत्तर
- Generators work on the principles of electromagnetic induction.
- For this the generator must be rotated.
- For this purpose, there is a turbine for each generator.
- This rotation needs energy. The turbines are different according to the type of energy source that is used for its rotation.
- Therefore, the construction of turbine is different for each power plant.
