Electrical Conducting Materials Ppt

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.

Electrical conducting materials ppt.

High purity copper is obtained by electrolytic refining. 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. Insulators materials through which electric current cannot move. Styrofoam rubber plastic paper what is resistance.

Electric current can flow easily through a material with high conductivity. Best quality of materials for rough usage with long last life. 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. In almost all studies conducting polymer films are developed and then electrical and mechanical properties are tested.
