1. Copper: Widely used in wiring due to its high conductivity.
2. Silver: Even more conductive than copper, but more expensive.
3. Gold: Excellent conductor, often used in electronics due to its resistance to corrosion.
4. Aluminum: Lighter than copper and often used in power lines.
5. Mercury: Liquid metal with good conductivity.
6. Graphite: A form of carbon with good conductivity, used in pencils and batteries.
7. Rubber: Common insulator used in electrical cords and gloves.
8. Glass: Used in electrical equipment like lightbulbs and insulators for power lines.
9. Plastic: Versatile insulator used in many applications, including phone cases and circuit boards.
10. Wood: A natural insulator, often used for building structures and furniture.
