- The definition of a conductor is a person who leads an orchestra, who is in charge of a train or streetcar or something that allows electricity to travel through it to complete a circuit.
- An example of a conductor is a maestro who leads the Boston Orchestra.
- An example of a conductor is someone who collects tickets on a San Francisco cable car.
An orchestra conductor during a performance.

conductor - Computer Definition
- A substance that allows electricity, light, heat, sound, or other forms of energy to pass through. In the context of telecommunications transmission systems, a conductor allows electric current or photonic energy to pass through.
- In fiber optics transmission systems, various highly specialized types of glass or plastic are used to conduct photonic energy. As dielectrics, glass and plastic are not conductors of electric current; therefore, optical fibers are immune to electromagnetic interference (EMI). See also EMI.
- In electric circuits, such as twisted pair and coaxial cable systems, a conductor is a material that readily permits the flow of electrons through itself in response to an electric field. Metals are excellent electrical conductors because of the high concentration of free electrons.Telecommunications networks most commonly use copper in electrified circuits, although copper-covered steel, copper alloy, nickel- or goldplated copper, and even aluminum metallic conductor are used. Gold, silver, and platinum are sometimes used in short circuits internal to various devices such as switches. CATV networks make use of aluminum and copper-clad aluminum in coaxial cable trunks. See also dielectric and insulator.

conductor - Science Definition
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.
