Which material is typically used for electrical wiring in homes?

Copper is commonly used for electrical wiring in homes due to its excellent conductivity, which allows electricity to flow efficiently with minimal resistance. This property ensures safe and reliable operation of electrical systems, reducing the risk of overheating or energy loss. Additionally, copper is relatively flexible, making it easier to work with during installation and repair. Its corrosion resistance also contributes to its longevity and reliability, which is crucial for maintaining the safety of electrical installations.

While aluminum is also used in some applications, it is less conductive than copper and can pose issues like thermal expansion and potential oxidation, which can compromise connections. Steel is not suitable for conducting electricity and is more typically used for structural applications. Plastic, although important for insulating wires and protecting against short circuits, does not conduct electricity and cannot be used as a material for wiring itself.
