... Conductors and Dielectrics Materials can be divided into two groups - conductors and dielectrics. In dielectrics, electrons are tightly bound to their hosts, the atoms or molecules keeping them neutral. If such material is exposed to the electric field, the molecules or atoms may rearrange themselv ...
