| conductor (kən-dŭk'tər) Pronunciation Key
A material or an object that conducts heat, electricity, light, or sound. Electrical conductors contain electric charges (usually electrons) that are relatively free to move through the material; a voltage applied across the conductor therefore creates an electric current. Insulators (electrical nonconductors) contain no charges that move when subject to a voltage. Compare insulator. See also resistance, superconductivity. |
A material through which electric current can pass. In general, metals are good conductors. Copper or aluminum is normally used to conduct electricity in commercial and household systems. (Compare insulator.)
