The best electrical conductor, under conditions of ordinary temperature and pressure, is the metallic element silver. Silver is not always an ideal choice as a material, however, because it is expensive and susceptible to tarnishing, and the oxide layer known as tarnish is not conductive.
A conductor is a substance in which electrons can move freely from one atom to another. An insulator is a substance in which electrons cannot move from one atom to another.

A conductor refers to a material that contains electrical charges on its surface, allowing electricity to flow through it. Most often, these electrical charges are due to the presence of electrons. A material's degree of conductivity depends on the number of charge carriers present, the amount of charge being ...
In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electrical current) in one or more directions.Materials made of metal are common electrical conductors. Electrical current is generated by the flow of negatively charged electrons, positively charged holes, and positive or negative ions in some cases.
So it is with electrical conductors, some being better than others. For instance, silver is the best conductor in the "conductors" list, offering easier passage for electrons than any other material cited. Dirty water and concrete are also listed as conductors, but these materials are substantially less conductive than any metal.
Non metals are poor conductors of heat and are not conductors of electricity , except for carbon , which is can conduct a little bit of electricity. Non metals are poor conductors of heat and are ...
Conductors and insulators are both important in the field of electronics. Electrical Conductors Electrical conductors allow electric current to flow easily because of the make up of their atoms. In a conductor, the outer electrons of the atom are loosely bound and can freely move through the material when an electric charge is applied.
Electrical conductors are materials with the special quality of containing electric charges that are conducive to conducting electricity. This electric charge, or free electrons, flows through the material when in the presence an electromagnetic field. This flow is called electric current. Most conductors are ...
This list of electric conductivity includes alloys as well as pure elements. Because the size and shape of a substance affect its conductivity, the list assumes all samples are the same size. In order of most conductive to least conductive:
CONDUCTORS AND INSULATORS. After reading this section you will be able to do the following: Contrast the characteristics of conductors and insulators. List examples of common conductors and insulators. Explain how insulators provide protection from electricity. In the previous pages, we have talked a bit about conductors and insulators .
