Charging of Insulators
Since charge cannot flow through insulators, neither conduction nor induction can be used to charge, insulators, so in order to charge an insulator friction is used. Whenever an insulator is rubbed against a body exchange of electrons takes place between the two. This results in appearance of equal and opposite charges on the insulator and the other body. Thus the insulator is charged.
For example rubbing of plastic with fur, silk with glass causes charging of these things.

Study Notes for Class 11 Physics Chapter 9 Mechanical Properties of Solids
Last modified on:5 years agoReading Time:10MinutesIntroduction All the rigid bodies are to some extent elastic. This means that their dimensions can be changed by pulling, pushing, twisting or by compressing them. e.g. When a helical spring is gently pulled at its both ends, the length of helical spring increases slightly. When we remove the forces applied…
