Brass is a good electrically conductive alloy. At 68 degrees Fahrenheit, it has a low resistance at around 0.6 to 0.9E-7 Ohm meter. One of its component metals is copper, which is only second best to silver in electric c... More »

Glass is not a good conductor of electricity and is classified as an insulator not a conductor. An electrical insulator is any material that does not allow electrons and electric charge to flow freely. These materials ma... More »

Brass does conduct electricity, but it is not a very good conductor. Not all metals conduct electricity to the same extent. Brass has a low electrical conductivity of only 28 percent, compared to metals such as silver an... More »

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 »

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 »

Saltwater is a good conductor of electricity because it is an electrolyte solution. Substances such as salts, acids and hydroxides that also are electrolytes can conduct electric current. Saltwater is a mixture that cons... More »

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... More »
