What metal is most commonly used to conduct electricity?

Copper is the most commonly used metal to conduct electricity due to its excellent electrical conductivity. It has a very low resistivity compared to other metals, which means it allows electric current to flow through it with minimal resistance. This property makes it ideal for use in wiring and electrical components.

In practical applications, copper wiring is widely used in homes, electronic devices, and power distribution systems, ensuring efficient energy transfer. Additionally, copper is relatively affordable and can be easily drawn into thin wires, making it a favored choice in electrical engineering and construction.

While gold also has high conductivity and is sometimes used in specific applications, particularly in connectors and circuit boards where corrosion resistance is essential, it is much more expensive. Silicon, on the other hand, is primarily used as a semiconductor in electronic devices rather than a conductor. Aluminum, though also a good conductor and lighter than copper, is less conductive than copper and tends not to be used in electrical wiring for high-capacity applications.
