Description of Electrical Conductors

A. Bhatia, B.E.

For the purpose of electronics and electrical engineering, materials are classified according to their electrical resistance, which describes how readily they allow electric current to pass when a voltage is applied. A conductor is a piece of metal used to conduct electricity. Apart from conductors, materials are classed as insulators (very poor conductors), semi-conductors (materials whose ability to conduct electricity can be controlled), and superconductors which (below a critical temperaure, usually cryogenic) offer no significant electrical resistance, allowing circular currents, once established, to flow indefinitely.

This 3-hr course provides general requirements, classifications and application information for electrical conductors. The course is based entirely on Naval Education and Training Materials (NAVEDTRA 14176), Electricity and Electronic Training Series; Module-4 and covers Chapter 1 titled “Electrical Conductors”.

The course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.
