insulation materials
Dielectric meterials are good insulator materials
A sharpener is not an insulator. Insulators are materials that do not easily allow the flow of electricity through them, while a sharpener is typically made of materials like metal or plastic which are conductive materials.
Insulator materials will not carry or conduct electricity.
Plastic, rubber, ceramic, glass.
A plastic bowl is an insulator.
Insulator
It will depend on the specific book and what materials have been used to create it. In most cases, a standard bound book of paper and standard cover will be an Insulator. With specific inks or metallic materials it could be a conductor.
Yes
A golf tee is an insulator. It is usually made of wood or plastic, which are materials that do not conduct electricity well.
Conductor
its an insulator
Since elastic is rubber and rubber is an insulator, then yes, elastic is an insulator.
