Conductors:
* Metals:
* Copper: Wiring, electrical components, plumbing
* Aluminum: Wiring, construction materials, cookware
* Silver: Jewelry, electrical contacts (high conductivity)
* Gold: Electronics, jewelry (resistance to corrosion)
* Water: Good conductor when containing dissolved salts (like in tap water). Pure water is a poor conductor.
* Human Body: Contains electrolytes, making it a conductor (which is why electric shock is dangerous).
* Graphite: Found in pencils and used in some batteries.
Insulators:
* Rubber: Used for electrical insulation in wires, gloves, and mats.
* Plastic: Widely used in electrical components, insulation, and consumer products.
* Glass: Found in windows, light bulbs, and electrical insulators.
* Ceramic: Used in electrical insulators, spark plugs, and heat-resistant materials.
* Wood: Used in construction, furniture, and as an insulator in some electrical applications.
* Paper: Used in capacitors, electrical insulation, and as a dielectric in some electrical components.
* Air: Acts as an insulator in most cases, but can become conductive if ionized (lightning).
Important Notes:
* Temperature: The conductivity of materials can change with temperature.
* Purity: Impurities in materials can affect their conductivity.
* Frequency: The conductivity of some materials can change at different frequencies of electrical current.
* It's vital to use the correct materials as conductors and insulators in electrical applications for safety and functionality.
