    10/04/2018· Silver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons). For a material to be a good conductor, the electricity passed through it must be able to move the electrons; the more free electrons in a metal, the greater its conductivity.

  • 10 Examples of Electrical Conductors and Insulators

    The best electrical conductor, under conditions of ordinary temperature and pressure, is the metallic element silver. It's not always an ideal choice as a material, however, due to its cost and because it tarnishes. The oxide layer known as tarnish is not conductive. Similarly, rust, verdigris, and other oxide layers reduce conductivity. The following are examples of effective

  • Electrical conductor Wikipedia

    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.
