GEOLOGY

Detailed explanation-1: -The charging by conduction process involves touching of a charged particle to a conductive material. This way, the charges are transferred from the charged material to the conductor. This method is useful for charging conductors.

Detailed explanation-2: -The process of transferring charge by touching or rubbing is called charging by contact. The rearrangement of electrons on a neutral object caused by a nearby charged object is called charging by induction.

Detailed explanation-3: -The process of transferring charge from a charged body to earth is called earthing.
