The best electrical conductor under conditions of ordinary temperature and pressure is the metallic element silver. Pure annealed copper is used for the winding of electrical machines. On the other hand electrically conductive materials such as aluminium powder graphite and carbon nanotubes have very interesting conductive properties and are promising in the synthesis of new composite conductive materials. The opposition to the flow of an electric current producing heat.

In almost all studies conducting polymer films are developed and then electrical and mechanical properties are tested. Best quality of materials for rough usage with long last life. Conductor semiconductor insulator are comes. 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.

Insulators materials through which electric current cannot move. Traces 0 1 of iron silicon or phosphorous seriously reduce the conductivity of copper.
