Electrical conducting materials ppt.

Insulators materials through which electric current cannot move. High purity copper is obtained by electrolytic refining. Energy band structures 5. The best electrical conductor under conditions of ordinary temperature and pressure is the metallic element silver.

In almost all studies conducting polymer films are developed and then electrical and mechanical properties are tested. Pure annealed copper is used for the winding of electrical machines. Electrical components wide range of electrical components for various domestic and industrial purposes. Styrofoam rubber plastic paper what is resistance.

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. Electrical conductivity conductivity defines a material s ability to conduct electricity. Sc 5 p 11 2 identify and classify materials that conduct electricity and materials that do not. In order of conductivity.

The opposition to the flow of an electric current producing heat. Traces 0 1 of iron silicon or phosphorous seriously reduce the conductivity of copper. Electric current can flow easily through a material with high conductivity. Electrical conducting materials copper.

Best quality of materials for rough usage with long last life. Conductor valence band only partially filled. 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. Conduits pipes an electrical materials used as the passage of wires for protection and insulation these could be rigid metallic flexible metallic conduit fmc rigid nonmetallic pvc and flexible non metallic or corrugated plastic conduit cpc.
