Methods

There are three ways to charge an object: friction, conduction and induction. Friction involves rubbing on material with another, resulting in electrons moving from one surface to another. Most people have experimented with this form of charging an object, either rubbing a balloon on a jumper to make it cling or by shuffling their feet over a carpeted surface to build up an electrical charge to shock someone. Friction is useful for charging insulators, which are materials that aren't good conductors. Conduction on the other hand is used to charge things that are good conductors, such a metal. A charged object is touched to the conductive material and some of the charge, whether it is positive or negative, will be transferred. The final way to charge an object is by induction and is, again, best for conductive materials. The uncharged conductive material is grounded on any neutrally-charged material and the charged object is held near it. The charge will flow between the two objects and the uncharged conductor will develop an opposite charge to the original charged object.
