Copper is an excellent conductor of electricity due to its atomic structure, which allows for the free movement of its outermost electron, resulting in high electrical conductivity. This is why copper is widely used in electrical wiring and electronic components. Aside from electricity, copper is also a very good conductor of heat. Its high thermal conductivity helps in distributing heat quickly and reducing localized overheating. Copper's conductivity properties rank just below silver, which is the best conductor, but copper is far more cost-effective and pliable, making it the preferred material for electrical and thermal conduction applications.
