Question

Which are the three main ways of charging a neutral object. Explain.

Accepted Answer

The presence of an equal amount of positive and negative charges in most objects is referred to as electrical neutrality. The charge balance of positive and negative charges must be altered to charge an object. The three methods are friction or rubbing, conduction, and induction.

The charging by friction method involves rubbing one particle against another, which causes electrons to move from one surface to the next. This procedure can be used to charge insulators. Touching a charged particle to a conductive medium is part of the charging by conduction process. Charges are transmitted from the charged substance to the conductor in this manner. This approach can be used to charge conductors. Finally, induction charging is a means of charging a thing without having to physically touch it with another charged object. The charged particle is held near an uncharged conductive material that is grounded on a neutrally charged material during the charging by induction procedure. When a charge transfers between two objects, the uncharged conductive material develops a charge that is the polar opposite of the charged object. An electroscope is frequently used to demonstrate the induction process of charging. A charged particle is brought close to but not touching the electroscope in this demonstration. The presence of a charged particle above the electroscope's plate causes the electrons in the electroscope to move. The electroscope is contacted while the charged particle is still held above the plate. The following key ideas can be summarised based on this demonstration:

The charged particle is never touched by the thing being charged through induction.

The charged object does not exchange electrons with or receive electrons from the charged object.
