Electrical Conductors
In physics and electrical engineering, a conductor is an object or type of material which permits the flow of electric charges in one or more directions. For example, an insulated wire is an electrical conductor as it can carry electricity along its length (but not across its width).
In metallic conductive materials such as copper or aluminum, the movable charged particles are electrons (see electrical conduction). 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. Insulators are non-conducting materials with few mobile charges and which support only insignificant electric currents.

Famous quotes containing the words electrical and/or conductors:
“Few speeches which have produced an electrical effect on an audience can bear the colourless photography of a printed record.”
—Archibald Philip Primrose, 5th Earl Rosebery (1847–1929)
“The great actors are the luminous ones. They are the great conductors of the stage.”
—Minnie Maddern Fiske (1865–1932)
