A conductor is a piece of metal used to conduct electricity, known colloquially as an electrical wire. Conductors are the means for tying the various components of an electrical or electronic system together. Many factors determine the type of conductor to be used in a specific application, including size, weight, cost, composition, resistivity, and the environment where the conductor will be used.
This course introduces the student to the general requirements, classifications, and application information for electrical conductors. It begins with a discussion of the standard units of measurement for determining conductor sizes and includes sample problems and solutions as an aid to learning the material. It also explains how to calculate the resistance (in ohms) of a conductor and how to use the American Wire Gauge (AWG) method for measuring wire size. Other important topics covered in the course are the most common types of insulation and protection for wire or cable conductors, as well as a comparison of some of the characteristics of copper and aluminum.
