Q2. How transformer works
Ans. 
Transformers work on the principle of electromagnetic induction to transfer electrical energy between two or more circuits.
• Transformers have two coils of wire, known as the primary and secondary coils.

• When an alternating current flows through the primary coil, it creates a changing magnetic field.

• This changing magnetic field induces a voltage in the secondary coil, transferring electrical energy between the coils.

Q5. Which wires we can use for earthing
Ans. 
Copper wires are commonly used for earthing due to their high conductivity and corrosion resistance.
• Copper wires are the most commonly used for earthing due to their high conductivity.

• Galvanized steel wires can also be used for earthing as they are durable and corrosion-resistant.

• Aluminum wires are another option for earthing, but they are less commonly used due to their lower conductivity compared to copper.

• The size a...read more
