* Rubber: Commonly used in electrical insulation, like the coating on wires.
* Glass: Found in light bulbs and other electrical components.
* Plastic: Used in a variety of electrical applications, including plugs and switches.
* Wood: A natural insulator often used in construction.
* Air: Acts as an insulator unless ionized.
* Paper: Used as insulation in capacitors and other devices.
* Ceramic: Often used in high-temperature applications and as insulators in electrical components.
* Diamond: An excellent insulator with exceptional hardness.
These materials resist the flow of electrical current due to their atomic structure. Their electrons are tightly bound to their atoms, making it difficult for them to move freely and carry an electrical charge.
