Q2. What is a transformer?
Ans. 
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
• Transformers are used to increase or decrease voltage levels in electrical circuits.

• They consist of two or more coils of wire wrapped around a core made of ferromagnetic material.

• Examples of transformers include power transformers used in electrical substations and distribution transform...read more

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.
• High voltage transmission lines operate at voltages above 69 kV, while low voltage transmission lines operate at voltages below 69 kV.

• High voltage transmission lines are used for long-distance power transmission, while low voltage transmissio...read more

Q1. How much distribution voltage
Ans. 
Distribution voltage refers to the voltage level at which electricity is distributed from substations to consumers.
• Distribution voltage typically ranges from 4 kV to 33 kV for residential and commercial areas.

• Higher distribution voltages, such as 66 kV or 132 kV, are used for industrial areas or large consumers.

• The choice of distribution voltage depends on factors like distance, load requirements, and cost.
