Insulators, also known as bad conductors, are materials that prevent electrons from freely flowing from one element’s particle to another. If we apply a charge to such an element at any point on the surface, the charge stays in the same place and does not spread across the surface. The common process of charging of such elements includes charging by rubbing and charging by induction. Distilled water does not conduct electricity because it does not contain any ionic compounds dissolved in it.
