What material is commonly used as a conductor in electrical wiring?

Copper is widely recognized as an excellent conductor in electrical wiring due to its superior electrical conductivity, which allows electric current to flow efficiently with minimal resistance. Its high conductivity, next to silver, makes it a preferred choice for electrical applications, ensuring minimal energy loss during transmission. Furthermore, copper is highly malleable and ductile, which makes it easy to work with during the manufacturing and installation of wiring. This material also resists corrosion, contributing to the longevity and reliability of electrical systems.

While aluminum is also a common conductor in some applications, particularly where weight savings are crucial, it does not match copper's conductivity. Gold, while an excellent conductor, is primarily used in specialized electronic applications where its resistance to oxidation is beneficial but is not practical for general wiring due to its high cost. Steel, on the other hand, has relatively low conductivity compared to copper and aluminum, making it unsuitable for electrical wiring applications.
