1. Electrical Insulators:
* Definition: Materials that resist the flow of electricity. They have a high resistance to the movement of electric charge.
* Examples:
* Rubber: Commonly used in electrical wires and cables.
* Glass: Used in electrical components, light bulbs, and insulators on power lines.
* Plastic: Used in a wide range of applications, from electrical plugs to circuit boards.
* Ceramic: Used in high-voltage insulators and spark plugs.
* Wood: Historically used in electrical installations but less common now due to its flammability.
2. Thermal Insulators:
* Definition: Materials that resist the flow of heat. They have low thermal conductivity, meaning heat transfers slowly through them.
* Examples:
* Fiberglass: Commonly used in home insulation and in building construction.
* Polystyrene (Styrofoam): Used in packaging, cups, and as insulation.
* Mineral Wool: Used in building insulation and fireproofing.
* Aerogel: Known for its extremely low thermal conductivity, used in specialized applications.
* Wool: A natural insulator used in clothing and home furnishings.
