Question

Dielectric material do not have free electrons

Answer 1

●During the formation of metallic materials, the electrons that are loosely bound to the nucleus are separated from their parent atoms and move in random manner. These are known as free electrons.

Materials which have plenty of free electrons are capable of conducting electricity and are called conducting materials.

Example: Metals like copper, silver etc.

Materials which do not have free electrons are not capable of conducting electricity are called non-conducting materials.

Example: Rubber, glass, plastic etc.

Answer:

Properties of Dielectric Material

The energy gap in the dielectric materials is very large.

The temperature coefficient of resistance is negative and the insulation resistance is high.

The dielectric materials have high resistivity.

The attraction between the electrons and the parent nucleus is very strong.
