Best quality of materials for rough usage with long last life. Jul 14 2020 conducting material and magenatic material ppt engineering semester notes edurev is made by best teachers of. Traces 0 1 of iron silicon or phosphorous seriously reduce the conductivity of copper. This document is highly rated by students and has been viewed 557 times.

Conductor semiconductor insulator are comes. Insulators materials through which electric current cannot move. Electrical conductivity conductivity defines a material s ability to conduct electricity. In almost all studies conducting polymer films are developed and then electrical and mechanical properties are tested.

The opposition to the flow of an electric current producing heat. Styrofoam rubber plastic paper what is resistance. In order of conductivity. 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.

Pure annealed copper is used for the winding of electrical machines. Electrical conducting materials copper. Conductor valence band only partially filled. Energy band structures 5.

A circuit tester is used to test whether the material is a good 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. 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. High purity copper is obtained by electrolytic refining.

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