| conductor |
With regard to passenger transport, a conductor is a person who sells and checks tickets on a bus, tram or train. In the case of a train, he or she is also responsible for safely closing the doors and signalling to the driver that the train is ready for departure; the conductor is the senior officer of a railway train, not the engineer/driver, as might be assumed. ...

In science and engineering, conductors are materials that contain movable charges of electricity. When an electric potential difference is impressed across separate points on a conductor, the mobile charges within the conductor are forced to move, and an electric current between those points appears in accordance with Ohm's law. While many conductors are metallic, there are many non-metallic conductors as well. ...

| conduction |
Transport of energy (charge) solely as a consequence of random motions of individual molecules (ions, electrons) not moving together in coherent groups. Conduction of energy is a consequence of temperature gradients; conduction of charge (electrical conduction) is a consequence of electric potential gradients. Conduction is distinguished from convection in which energy (or charge) is transported by molecules (ions, electrons) moving together in coherent groups.

| conductivity |
1. A unit measure of electrical conduction; the facility with which a substance conducts electricity, as represented by the current density per unit electrical-potential gradient in the direction of flow. Electrical conductivity is the reciprocal of electrical resistivity and is expressed in units such as mhos (reciprocal ohms) cm -1 . It is an intrinsic property of a given type of material under given physical conditions (dependent mostly upon temperature). ...
