Question

differentiate between charging by conduction and charging by induction​

Answer 1

Charging by conduction involves the contact of a charged object to a neutral object. ... In contrast to induction, where the chargedobject is brought near but never contacted to the object being charged, conduction charginginvolves making the physical connection of thecharged object to the neutral object

Answer 2

Charging by Induction

The previous section of Lesson 2 discussed the process of charging an object by friction or rubbing. Friction charging is a very common method of charging an object. However, it is not the only process by which objects become charged. In this section of Lesson 2, the charging by induction method will be discussed. Induction charging is a method used to charge an object without actually touching the object to any other charged object. An understanding of charging by induction requires an understanding of the nature of a conductor and an understanding of the polarization process. If you are not already comfortable with these topics, you might want to familiarize yourself them prior to reading further.


Charging by Conduction

In the previous two sections of Lesson 2, the process of charging by friction and charging by induction were described and explained. In this section of Lesson 2, a third method of charging - charging by conduction - will be discussed. As was the case for charging by friction and charging by induction, the process of conduction will be described and explained using numerous examples of electrostatic demonstrations and lab experiments.

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. Or suppose that a negatively charged metal sphere is touched to the top plate of a neutral needle electroscope. The neutral electroscope becomes charged as the result of being contacted by the metal sphere. And finally, suppose that an uncharged physics student stands on an insulating platform and touches a negatively charged Van de Graaff generator. The neutral physics student becomes charged as the result of contact with the Van de Graaff generator. Each of these examples involves contact between a charged object and a neutral object. In contrast to induction, where the charged object is brought near but never contacted to the object being charged, conduction charging involves making the physical connection of the charged object to the neutral object. Because charging by conduction involves contact, it is often called charging by contact.
