Question

A material in which electrons are tightly bound and cannot move freely at room temperature is called

Answer 1

Insulators:

• An electrical insulator is a substance that does not conduct electricity.
• In insulators, the electrons are tightly bound and cannot move freely at room temperature.
• Examples of insulators are plastics, paper, and rubber.

Properties of insulators:

• Non-metallic solids tend to be good insulators.
• They have high resistivity in comparison to conductors as well as semi-conductors.
