In general, conductivity refers to the capacity of a substance to transmit electricity or heat. A conductor conducts electricity since it offers little or no resistance to the flow of electrons, thus leading to a flow of electricalcurrent. Typically, metals, metal alloys, electrolytes and even so...

This property also applies to the transmission of heat and sound. Conductance tells about to what extent an object conducts electricity, expressed in units of Siemens. It is measured as the ratio of the current that flows to the existing potential difference. It depends on the dimensions of ...
A semiconductor is a material product with some of the properties of both insulators and conductors (hencesemi,meaning half or partial, conductor). Semiconductors are usually comprised of silicon, since this conducts electricity more than an insulator, such as glass, but less than a pure conductor...
(Physics) A substance or medium that conducts heat, light, sound, or especially an electric charge. Insulators A material that insulates, especially a nonconductor of sound, heat, or electricity. Conductors A lightning rod, as on a house or barn. Insulators A device that insulates. Conductors...
A semiconductor is a substance that has specific electrical properties that enable it to serve as a foundation for computers and other electronic devices. It is typically a solid chemical element or compound that conducts electricity under certain conditions but not others. This makes it an ideal ...
Copper contains metallic bonds and so conducts electricity. Rubber contains covalent bonds and so does not conduct electricity. It protects the user from getting an electric shock. Chin Trento Chin Trento holds a bachelor’s degree in applied chemistry from the University of Illinois. His educational...
Superconductor is an element, inter-metallic alloy, or a compound that conducts electricity without resistance below a certain temperature. Once set in motion, electrical current will flow forever in a closed loop of a superconducting material. ...

readily). It can be used to sort materials by type as well. Resistivity has its uses as well. Of these, perhaps the best known is the use of rubber as an electrical insulator. Insulators are materials used to surround conductors to prevent the passage of electricity or heat out of the ...
