* Rubber: Used in electrical cords and gloves for protection.
* Plastic: Commonly used in electrical components and housings.
* Glass: Used in light bulbs and other electrical devices.
* Wood: A natural insulator used in construction and furniture.
* Ceramic: Found in electrical insulators, spark plugs, and other high-temperature applications.
* Air: Acts as an insulator under normal conditions.
* Paper: Used as insulation in electrical wires and capacitors.
* Diamond: An excellent insulator due to its strong covalent bonds.
* Pure water: While water can conduct electricity when impurities are present, pure water is an excellent insulator.
Why are some materials insulators?
Insulators have a unique atomic structure that prevents the free flow of electrons, which are responsible for carrying electrical current. In insulators, electrons are tightly bound to their atoms and cannot move freely.
Note: No material is a perfect insulator. Even the best insulators can conduct a small amount of electricity under extreme conditions like high voltage or extreme temperatures.
