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 ... More » Science Physics Electricity

Citric acid is not a good conductor of electricity. This is because it is an example of a weak acid, which breaks down in water quickly. More » Science Physics Electricity

Graphite is a good conductor of electricity because its electrons are delocalized or free to move around. Graphite is structured into planes with tightly bound atoms. There is a great deal of distance between planes, and... More » Science Physics Electricity

Iron is a good conductor of electricity but not the best. Iron is a metal, which makes it a much better conductor than an insulator, but different metals have different conductivity levels. Iron is a relatively cheap met... More » Science Physics Electricity
