What do you mean by conductivity of metals

In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electrical current) in one or more directions. Materials made of metal are common electrical conductors.

Explanation:

Electric conductivity is the movement of electrically charged particles. All metals conduct electricity to a certain extent, but certain metals are more highly conductive. The most highly conductive metals are silver, copper, and gold. Copper, for example, is highly conductive and commonly used in metal wiring.
