Wires are thin strands of metal, often made of copper or aluminum, that are used to conduct electricity. They are essential for powering our homes, devices, and appliances. Wires can be found in everything from light bulbs to computers, connecting different parts to ensure they work together efficiently. In addition to electricity, wires can also transmit data. For example, telephone wires carry voice signals, while fiber optic cables use light to send information over long distances. Wires come in various sizes and types, each designed for specific tasks, making them a crucial part of modern technology and communication.
