* Rubber: Used in electrical cords and gloves to prevent shocks.
* Plastic: Found in many everyday items like phone cases and water bottles.
* Glass: Used in light bulbs and other electrical components.
* Wood: Commonly used in construction and furniture.
* Paper: A common insulator used in many applications.
* Air: A good insulator unless it becomes ionized (like in a lightning strike).
* Diamond: A very strong insulator, used in electronics.
Why are these materials insulators?
Insulators have tightly bound electrons that are not easily freed to move and carry an electrical current. In contrast, conductors like metals have free electrons that can easily move and carry a current.
