How is charging by induction different from charging by conduction?
Charging by conduction can transform a neutral object into a charged to object.
Charging by induction requires direct contact with the object while charging by conduction does not.
Charging by conduction requires direct contact with the object while charging by induction does not.
Charging by induction distributes the electron from one object to another.
