Insulators charged by friction -when two insulators move relative to each other, friction between the two can result in both objects becoming electrically charged -one of the objects becomes positively charged and other is negatively -eg plastic being rubbed against duster -conductors can become charged but will only retain that charge of they are insulated from their surroundings. If not insulated, then any charge that builds up will leak away Charging by induction it's possible for obje...
