Copper wire is a type of electrical conductor made from the metal copper. It is widely used in electrical wiring due to its excellent conductivity, which allows electricity to flow easily. Copper wire is often found in homes, appliances, and electronic devices, making it essential for modern technology. The wire comes in various gauges, indicating its thickness, which affects its current-carrying capacity. Thicker wires can handle more electricity, while thinner wires are suitable for lighter loads. Copper wire is also resistant to corrosion, ensuring durability and reliability in electrical applications.
