Five insulating materials

Electric charges do not flow freely through insulators. This is an ideal quality in many cases—strong insulators are often used to coat or provide a barrier between conductors to keep electric currents under control. This can be seen in rubber-coated wires and cables. The most effective electrical insulators are: 1. … See more Valence electronsare like outer planets orbiting a star. They're attracted enough to their atoms to stay in position but it doesn't always take a lot of energy to knock them out of place—these electrons easily carry electric currents. … See more The best electrical conductor, under conditions of ordinary temperature and pressure, is the metallic element silver. Silver is not always an ideal choice as a material, however, … See more The shape and size of a material affect its conductivity.
