This is a list of 10 examples of materials that are electrical conductors and insulators and a look at why some materials conduct better than others.
List of Conductors and Insulators A conductor is a substance in which electrons can move freely from one atom to another. An insulator is a substance in which electrons cannot move from one atom to another.
In addition to the strong conductors listed above, other conductors include gold, iron, steel, brass, bronze and mercury. While materials generally fall into the category of being either a conductor or an insulator, some materials are both.
In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electrical current) in one or more directions.Materials made of metal are common electrical conductors. Electrical current is generated by the flow of negatively charged electrons, positively charged holes, and positive or negative ions in some cases.
A list of electricity conductors would probably start with gold and progress through a list of all the metals and then through several other minerals in order of their specific resistance. The common materials used as electricity conductors are co...
A bad electrical conductor is an object or material that does not allow electricity to flow freely through it. An insulator does not allow electric current to pass through it. Most metals, such as copper, are good conductors, whereas most other non-metal materials are bad conductors, or insulators.
Electric conductivity is the movement of electrically charged particles. All metals conduct electricity to a certain extent, but certain metals are more highly conductive. The most highly conductive metals are silver, copper, and gold. Copper, for example, is highly conductive and commonly used in metal wiring.
So it is with electrical conductors, some being better than others. For instance, silver is the best conductor in the "conductors" list, offering easier passage for electrons than any other material cited. Dirty water and concrete are also listed as conductors, but these materials are substantially less conductive than any metal.
CONDUCTORS AND INSULATORS. After reading this section you will be able to do the following: Contrast the characteristics of conductors and insulators. List examples of common conductors and insulators. Explain how insulators provide protection from electricity. In the previous pages, we have talked a bit about conductors and insulators .
The way a material has been processed can affect how well it conducts electricity. Electromagnetic fields: Conductors generate their own electromagnetic fields when electricity runs through them, with the magnetic field perpendicular to the electric field. External electromagnetic fields can produce magnetoresistance, which can slow the flow of ...
