What is insulator ?.

Any material that keeps energy such as electricity, heat, or cold from easily

transferring through is an insulator.

Insulators consist of different types of insulator materials like plastic, rubber, mica, wood, glass, etc. In the electrical system, specific insulating materials are used like porcelain, glass, steatite, polymer, ceramic, PVC.

Property 1: In an insulator, the valence electrons are tightly held together.

Property 2: The ability of the material to not allow the electric current to pass through it is called electrical resistance.

Property 3: Insulators have large dielectric strength.

An insulator is a material that does not conduct electrical current. Insulating materials include paper, plastic, rubber, glass and air.
