Wires are essential components in electrical systems, serving as conduits for electrical currents to flow from one point to another. Available in various materials such as copper, aluminum, and steel, wires are used in everything from household appliances to complex industrial machinery. Copper wires, known for their excellent conductivity, are commonly used in most wiring applications, while aluminum wires are favored for their lightweight and cost-effective properties in certain installations. Wires come in different gauges, which determine their capacity to carry electrical current, making it crucial to choose the right wire size for each specific application.
