In general, metals make good conductors of electricity. These include copper, gold, silver and aluminum. Copper is a common conductor of electricity used in industrial applications because it is inexpensive to acquire, especially in comparison to gold and silver. Aluminium is not as efficient in con
Iron is a conductor of electricity. Its electrical resistivity is 9.71 microohm centimeter. In comparison to copper, it is a poorer conductor of electricity. Nevertheless, generally, it is considered a good conductor of electricity.
Glass, paper, Teflon and rubber are good insulators of electricity. An insulator is a substance that allows very little electric current to flow through it. There is no perfect insulator, but materials that offer a high degree of resistance to the flow of electrons are good insulators.
Gold is a very good conductor of electricity. It is often used as plating for connectors because it does not tarnish or corrode easily.
Copper is a good conductor of electricity because the valence electrons are free and repel each other so strongly that it causes the repulsion of other electrons. This essentially forces the electricity down the piece of copper, or conducts it down the metal.
Metals are good conductors of electricity because their atoms contain at least one free electron. They are also considered excellent heat conductors, because the metal ions in the lattice are closely packed together, and the delocalized electrons can bring kinetic energy through the lattice.
Although many people think water conducts electricity well, pure water is a poor conductor since its molecules do not have free electrons to travel and thus transfer current. Pure water, however, rarely exists in nature. Salts, sediments and minerals often mix with water and create ions that conduct
Sodium is a soft, silver-white metallic element known for its electrical and thermal conductivity. At room temperature sodium is waxlike in composition and is malleable and ductile. Sodium must be derived through chemical means, as it is not found freely in nature.
Although metals are supposed to be good conductors of electricity and heat, metals like mercury, lead, alloys of iron and chromium, titanium and stainless steel are poor conductors when compared to silver, copper and gold. For example, stainless steel 310 has an electrical conductivity of 1.28 x 10E
Examples of conductors include the human body, metals, aqueous solutions of salt, graphite, copper, silver and gold. Conductors are materials that can transfer heat and transmit electricity. Conductors have a high density, allowing particles to flow freely and collide.
