Electrical Conducting Materials Ppt

Electric current can flow easily through a material with high conductivity.

Electrical conducting materials ppt. Conductor semiconductor insulator are comes. Electrical shock occurs when the body becomes part of the electric circuit either when an individual comes in contact with both wires of an electrical circuit one wire of an energized circuit and the ground or a metallic part that has become energized by contact with an electrical conductor. 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. In order of conductivity.

Conductor valence band only partially filled. Electrical conducting materials copper. 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.

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. Electrical conductivity conductivity defines a material s ability to conduct electricity. 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. Pure annealed copper is used for the winding of electrical machines.

Best quality of materials for rough usage with long last life. A circuit tester is used to test whether the material is a good electrical conductor. Energy band structures 5. In almost all studies conducting polymer films are developed and then electrical and mechanical properties are tested.

High purity copper is obtained by electrolytic refining. Insulators materials through which electric current cannot move. Electrical components wide range of electrical components for various domestic and industrial purposes. Sc 5 p 11 2 identify and classify materials that conduct electricity and materials that do not.
