Electrical wires are conductive materials, usually made of metals like copper or aluminum, that carry electric current from one point to another. They are essential components in electrical systems, allowing electricity to flow to devices such as lights, appliances, and computers. Wires are often insulated with plastic or rubber to prevent accidental shocks and short circuits. Wires come in various sizes and types, each designed for specific applications. For example, power cables are used for high-voltage transmission, while communication wires are used for data transfer in telecommunication systems. Proper installation and maintenance of electrical wires are crucial for safety and efficiency.
