Examples of conductor in the following topics:

  • Conductors

    • A conductor is a material which contains movable electric charges.
    • In describing conductors using the concept of band theory, it is best to focus on conductors that conduct electricity using mobile electrons.
    • Most familiar conductors are metallic.
    • Silver is the best conductor, but it is expensive.
    • However, some non-metallic materials are practical electrical conductors without being good thermal conductors.
  • Semiconductors

    • Semiconductors are materials that have properties in between those of normal conductors and insulators; they are often produced by doping.
    • Semiconductors are materials that have properties of both normal conductors and insulators.
    • When a semiconductor is doped to such a high level that it acts more like a conductor than a semiconductor, it is referred to as degenerate.
    • Compare N-type and P-type semi-conductors, distinguishing them from semi-conductors and insulators using band theory.
  • General Properties of Metals

    • A metal can refer to an element, compound, or alloy that is a good conductor of both electricity and heat.
    • A metal can refer to an element, compound, or alloy that is a good conductor of both electricity and heat.
  • Properties of Carbon

    • Diamond is transparent, the ultimate abrasive, and can be an electrical insulator and thermal conductor.
    • Conversely, graphite is opaque, a very good lubricant, a good conductor of electricity, and a thermal insulator.
  • Mercury

    • Compared to other metals, mercury is a poor conductor of heat, but a fair conductor of electricity.
  • Allotropes of Carbon

    • Uses of diamond include cutting, drilling, and grinding; jewelry; and in the semi-conductor industry.
    • Graphite is another allotrope of carbon; unlike diamond, it is an electrical conductor and a semi-metal.
    • Carbon nanotubes are cylindrical carbon molecules that exhibit extraordinary strength and unique electrical properties and are efficient conductors of heat.
  • Electrolytic Cells

    • Two electrodes: an electrical conductor that provides the physical interface between the electrical circuit providing the energy and the electrolyte.
  • Bonding in Metals: The Electron Sea Model

    • Metals are good conductors of electricity because the electrons in the electron sea are free to flow and carry electric current.
  • Elemental Boron

    • Amorphous boron is a brown powder, while crystalline boron is black, extremely hard (about 9.5 on the Mohs scale), and a poor conductor at room temperature.
  • Electrolyte and Nonelectrolyte Solutions

    • By contrast, if a compound dissociates to a small extent, the solution will be a weak conductor of electricity; a compound that only dissociates weakly, therefore, is known as a weak electrolyte.
