WebApr 11, 2024 · Conductors have a very low resistance to electric current. Insulators or Bad Conductors . Atoms in materials such as rubber have tightly bound electrons, which prevent the flow of electricity. Insulators or Bad/Poor conductors, thus, are materials that do not allow free and easy flow of ions and electrons from atom to atom. WebThere are electrons in a conductor that can move about relatively freely. These can move around with almost no resistance, whereas for insulators a key difference is that these electrons cannot move around freely.
