1) One theory about charging insulators is called adhesion. Look this up and explain (in about 3-4 sentences) why charge transfers between two insulators that are rubbed together. 2) Describe what happens to the charge on a neutral metal sphere if a charged rod is brought near (but not touching) the sphere. 3) Does the sphere in the previous question remain neutral?

Types of Charge Carriers

A carrier is a type of object which carries a particular thing from one point to another point. For instance, people use different vehicles from one place to another, and the vehicle carries those people and acts as a carrier.
