1. Rubber: Used in electrical cords and gloves for protection from electrical shocks.
2. Glass: Used in windows, light bulbs, and other applications where electrical conductivity is undesirable.
3. Plastic: Widely used in electronics, appliances, and packaging due to its insulating properties.
4. Wood: Commonly used in construction and furniture, providing insulation against electricity.
5. Air: A good insulator, preventing electrical current from flowing through it (except in cases of lightning).
1. Copper: Widely used in electrical wiring, motors, and other applications due to its excellent conductivity.
2. Silver: Even more conductive than copper, often used in specialized applications like high-frequency circuits.
3. Gold: Resistant to corrosion, often used in electronics and jewelry.
4. Aluminum: Lightweight and good conductor, used in power lines and foil.
5. Water: A good conductor, especially when containing impurities like salts.
