conduction and insulation I had given pic

Answer 2

*Definition of Conductor*

The conductor is defined as the material which allows the electric current or heat to pass through it. The electrons in a conductor freely moved from atom to atom when the potential difference is applied across them. The conductivity of the conductor depends on the number of free electrons in the outermost shell of the orbit. The conductivity of the material is directly proportional to the number of free electrons.

Examples: Irons, aluminum, silver, copper, etc.

*Definition of Insulator*

The materials which do not allow the electric current or heat to pass through it such type of material is called an insulator. The covalent bond between the atoms of an insulator is very strong.Thus, the electrons or charges do not move freely. The resistivity of the insulator is very high.The forbidden gap between the valence band and conduction band of an insulator is very large, and hence the electrons require large energy for moving from valence band to conduction band.The insulator is mainly used for separating the conductor and for supporting the electrical equipment. It is also used in an electrical cable. Paper, wood, porcelain, etc., are some of the examples of an insulator.

Examples:. Rubber, wood, Paper, etc.
