Water can easily conduct electricity if it contains ionic compounds, but pure water does not conduct electricity. Pure water is rarely found in nature, therefore the majority of water found on Earth does conduct electricity.
The most common materials that are good conductors of electricity are metals, but other materials, such as carbon, can also conduct electricity in certain forms. When carbon atoms are arranged in a certain structure like graphene, they can conduct electricity well, but are poor conductors in materia
Oils conduct electricity minimally under normal conditions, which makes them useful as insulators. The extent of electrical conductivity depends on the concentration of impurities. The presence of salts and other substances generally increases the electrical conductivity of oil.
Common electrically conductive elements include silver, copper, gold, iron, zinc, platinum and nickel as well as many other metal elements. The most electrically conductive element of all is silver, the second-most conductive element is copper, and the third-most conductive element is gold.
The metals that conduct electricity the best are silver, copper and aluminum. Both copper and aluminum are used extensively in electrical wiring. Silver, though it conducts electricity better than either of the other two, is too expensive for common usage.
Carbon is the only nonmetal outside of the metalloid group that conducts electricity. Metalloids are a group of related nonmetal elements with some metal traits, including the ability to conduct electricity. Other nonmetals are electrical insulators.
There is no metal that does not conduct electricity entirely, but there are some metals that are less effective conductors than others. Metal atoms have electrons in their outer shells that are not tied to any particular atom and can flow freely within the metal when electricity is applied.
Metals conduct electricity well due to the fact that the outermost electrons in their atoms are held by weak atomic forces, allowing these electrons to flow easily from one atom to another. This flow of electrons is what lies at the heart of an electric current.
Wood is classified as an insulator and does not readily conduct electricity, but when wet, wood does have the potential to conduct electricity. Insulators resist the flow of electricity, as stated by the Occupational Safety and Health Administration.
Plastics are known for their very poor ability to conduct electricity; however, a new type of plastic has now been shown in studies to conduct electricity well. This means that plastics can now be made to either conduct electricity or not to conduct electricity.
