Electrical conductivity measures a material's ability to allow the flow of electric current. Copper has exceptionally high electrical conductivity, meaning it offers low resistance to the movement of electrons. This property ensures efficient transmission of electricity with minimal energy loss due to resistance heating.
High electrical conductivity is crucial for electrical cables as it reduces power loss during transmission and distribution. Copper's excellent conductivity makes it the preferred material for various electrical applications, including wiring, cables, motors, generators, and transformers.
