Electrical Material represents the parts or the elements that are
used in order to make each and every electrical structure from a house
circuit to a big factory. Electrical Materials can be the electrical
fittings, the lugs, electrical circuit breakers, the motor control, the
electrical conduit, the lighting or the enclosures.
The Electrical Material contains all the time movable electric charges. In the electrical metallic conductors, like the copper or aluminum ones, the movable electric charged particles represent the electrons. The positive movable electric charges are in the form of atoms. All the electric conductors are containing movable electric charges that will move in case that a potential difference is applied in separate points on the electrical material. This flow of electric charge represents the electric current. In most of the materials, the actual rate of the current is direct proportional to the voltage, provides the temperature to remain constant, in order that the electric material doesn't changes it's shapes and sizes.
The most known electrical conductors are the metallic ones; copper is the most common used material for all the wiring. Silver is the best conductors, but is also very expensive, and the gold as electric material is very good for the high quality surface-to-surface electrical contacts. There are also many conductors that are not metallic, such as graphite, solutions of salts and all the plasmas. All these electrical materials will offer some resistance and also some warm up when an electrical current will flow through them. The design of any electrical conductor is taking into consideration the temperature that the conductor will need to be able to endure without any damage, as well as the actual quantity of the electrical current that will flow.
The thermal and the electric conductivity will often go together (for example, many metals can be both electrical and thermal conductors). However, many materials can be electrical conductors without having good thermal proprieties.
In most of the countries from around the world, the electrical conductors are measured by the cross section in square millimeters. However, in the United States, the conductors are measured by the American Standard Wire Gauge for the smaller ones and by the Circular Mils for the larger ones.
The voltage on an electric conductor is mostly determined by the whole connected circuit, and not by the connector, itself. The electrical conductors are surrounded, or even supported, by the insulators, and only the insulation can determine the maximum voltage that can, and will be applied to any electrical conductor.
