- Q3. How does a thermal power plant work ?
- Ans.
A thermal power plant generates electricity by converting heat energy into electrical energy.
Fuel (such as coal, natural gas, or oil) is burned to produce heat
The heat is used to boil water and produce steam
The steam drives a turbine connected to a generator, which produces electricity
The electricity is then transmitted through power lines to homes and businesses
- Q4. What is the difference between high voltage transmission line and low voltage transmission line?
- Ans.
High voltage transmission lines carry electricity over long distances with minimal energy loss, while low voltage transmission lines distribute electricity to homes and businesses.
