Explain the various methods of charging an object


proper answer of this question an get a chance to be a brainlist​

Answer 1

Answer:

Methods. There are three ways to charge an object: friction, conduction and induction. ... Conduction on the other hand is used to charge things that are good conductors, such a metal. A charged object is touched to the conductive material and some of the charge, whether it is positive or negative, will be transferred.

Answer 2

There are basically three methods known for charging an object :

▫️Charging by Friction

• This methods includes rubbing of two object that require no charge that is are completely neutral.
• On providing friction the charge transfer occurs and one body gets positively charged while another gets negatively charged as it gains an electron while former loses the electron pair.
• Examples : Rubbing a silk cloth on plastic rod gives the silk cloth negative charge while rod gets the positive charge.

▫️Charging by Conduction

• As the name suggest a neutral body acquires the similar charge as the one which is responsible for charging it.
• To simplify the above sentence for the further a neutral sphere is taken and a positively charged body is brought near , after sometime we observe that the sphere requires the similar positive charge.
• The the actual phenomenon of conduction takes place and neutral sphere holding both positive and negative child becomes positively charged because the negative charges are attracted by the the positively charged plate or any body that is brought near it.

▫️ Charging by Induction

• The charges get induced on other body which is completely uncharged due to the influence of a charged body.
• Here no physical contact of the two bodies occur but due to the influence everything happens.
• To explain it more clearly imagine a positively charged sphere is brought near a neutral sphere after sometime we observe that the neutral sphere aquires the negative charge at the near corner where the the positively charged sphere is placed (no contact between them ) .

Marks of Differences

1. In process involving charging by induction contact is made between two bodies but in case of friction and conduction bodies are brought in contact with each other.

2 . No rubbing occurs in either of the process except fiction where two bodies are constantly rubbed against each other and are made to acquire some charges.
