The metal most commonly used in electrical wiring is copper. Due to its excellent conductivity, copper is favored for electrical applications, allowing electricity to flow with minimal resistance. Its durability and resistance to corrosion make it an ideal choice for wiring in both residential and industrial settings. While aluminum is also used for electrical wiring, particularly in high-voltage applications, copper remains the preferred material for most wiring tasks. The efficiency and reliability of copper wiring have contributed significantly to the overall effectiveness of electrical systems worldwide.
