How are charges generated?
Advertisements
उत्तर
Charges are generated in an object when the object loses or gains some electrons or when there is displacement between the positive and negative charges of an object. Methods of generating charges are:
- Rubbing: Explains how friction between insulators causes electron transfer, resulting in one object being positively charged and the other negatively charged.
- Conduction: Describes how contact with a charged body can transfer charge to an uncharged conductor.
- Induction: Illustrates how a nearby charged body can cause temporary separation of charges within a neutral body, resulting in a temporary charge.
