1)What is the energy conversion that takes place in a turbine in a power plant?

2. A generator works on the principle of electromagnetic induction.
3. In a nuclear power plant, nuclear reactions are used for converting water into steam.
4. A standard steam power plant is more efficient than Cogeneration.
