Conductors are materials that can easily conduct electricity so that the conductor is often referred to as a good conductor of electricity. On a good conductor, the number of free electrons, the electrons that have a large enough energy (located at the outermost track) is banyakdan free to move, eg in copper materials, each copper atom contributes one free electron.
Copper as a substance that has the atomic number 29, has a free electron in charge of this terluarnya.elektron skin to conduct electricity when the conductor of the rated voltage
Conductor in electronics engineering is a substance that can conduct electrical current, either solid, liquid or gas. Because it is conductive, it is called a conductor. A good conductor has a small resistivity. Conductors are materials that are very good ability to conduct electricity, almost all metals are metallic conductors.
examples of several types of conductors
Examples of conductors include gold, silver, copper, aluminum, zinc, iron successively growing resistance, type. So as gold is a very good conductor, but because it is very expensive price, the economically copper and aluminum are the most widely used
