The substance known as a conductor of electricity is copper. Copper is widely used in electrical wiring because of its excellent conductivity, malleability, and resistance to corrosion. It allows electric current to flow easily, making it the preferred choice for electrical applications in homes, appliances, and electronic devices. The atomic structure of copper provides free electrons that facilitate the flow of electricity. While other materials, such as aluminum and silver, can also conduct electricity, copper remains the most common due to its balance of conductivity, cost-effectiveness, and durability.
