Q2. What is 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 coils of wire, known as the primary and secondary coils, wrapped around a core.

• Step-up transformers increase voltage levels, while step-down transformers decrease voltage levels.

Q3. What is resistance
Ans. 
Resistance is the opposition to the flow of electric current.
• Resistance is measured in ohms (Ω).

• It is caused by the collisions of electrons with atoms in a conductor.

• Higher resistance leads to lower current flow.

• Resistance can be affected by factors like material, length, and temperature.

• Examples of high resistance materials include rubber and glass.

• Examples of low resistance materials include copper and silver.
