There are four methods by which charges can redistribute themselves to build up static electricity: by friction, by conduction, by induction, and by polarization.
Q. What are two possible ways that a charged object can be discharged?
Explanation: This process takes a minute or two, much faster is the discharge we know of as a spark. Charged objects may also discharge via contact with a conductor connected to earth (or an oppositely charged object.)

Q. How can objects be discharged?
Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. One way to discharge them is through a circuit. Remember, objects with the same charge repel each other.
Q. Can a grounded object have nonzero charge?
Not necessarily. For example, if there is another nearby charge, the conductor may need to gain charges so as to nullify its potential. A grounded conductor has the potential of the ground which is assumed to be zero. But it does not imply that charge will also be zero on this conductor.
Q. What is the movement of charge when a positively charged object is grounded out?
Grounding is the grounding of a positively charged object and involves the transfer of electrons from the ground into the object. The excess of positive charge on the object attracts electrons from the ground.

- Objects can become Charged by. Contact and Induction:
- Charged by Contact (Touching):
- Charged by Induction (No Touching):
- Charged objects can become Discharged by. Sparking and Grounding:
- Even the CN Tower uses Grounding!!!
Q. What happens when a positive object touches a neutral object?
Charging by conduction involves the contact of a charged object to a neutral object. Suppose that a positively charged aluminum plate is touched to a neutral metal sphere. The neutral metal sphere becomes charged as the result of being contacted by the charged aluminum plate.
Q. Which will a positively charged object attract?
Any charged object – whether positively charged or negatively charged – will have an attractive interaction with a neutral object. Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other.
Q. Why is anode positive and anion negative?
The battery pumps electrons away from the anode (making it positive) and into the cathode (making it negative). The positive anode attracts anions toward it, while the negative cathode attracts cations toward it.
Q. How can you tell if a salt is a cation or anion?
Inorganic salts can be obtained with a base through complete or partial neutralization of acid. The part that the acid contributes is called anion in the formation of a salt and the part that the base contributes is called cation.
