conductors in Science

conductor

[kən-dŭktər]
  1. 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.
