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 »

Metals are good conductors of electricity, because they have free electrons. These free electrons act as charge carriers in the metallic structure, allowing electric current to flow through the metal. More »

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 »

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 »

Graphite conducts electricity because it possesses delocalized electrons in its structure. The honeycomb layout of the stacked carbon atoms of graphite leaves a single electron unbound in each hexagon. Each of these elec... More »

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.... 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 »
