Question: 1 / 400

Which metal among those listed is known for its significant use in electronics and wiring due to its high conductivity?

Copper

Copper is well-known for its high electrical conductivity, which makes it the preferred choice for wiring and electronics. Its ability to efficiently conduct electricity allows for minimal energy loss, which is critical in electrical applications. This metal is abundant and relatively inexpensive compared to others, making it highly practical for use in power cables, circuit boards, and electronic components. While gold also has excellent conductivity and is sometimes used in high-end electronics and connections for its resistance to corrosion, copper remains the standard for most applications due to its balance of cost, conductivity, and availability. Other metals such as zinc and cobalt do not exhibit the same level of conductivity, which limits their use in electrical applications compared to copper.
