In physics and electrical engineering, a conductor is an object or type of material that allows the flow of electrical current in one or more directions. For people, a wire is an electrical conductor that can carry electricity along its length.In metals such as copper or aluminum, the movable charged particles are electrons.Positive charges may also be mobile, such as the cationic electrolyte (s) of a battery, or the mobile protons of the proton conductor of a fuel cell.n metals such as copper or aluminum, the movable charged particles are electrons.

Conductors and Insulators. In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them.Conductor implies that the outer electrons of the atoms are loosely bound and free to move through the material.ny external influence which moves one of them will cause a repulsion of other electrons which propagates, domino fashion through the conductor. Simply stated, most metals are good electrical conductors, most nonmetals are not.
