insulator does not have free electrons.....so if insulators are rubbed ...there must be no transfer of electrons...how they can be charged by rubbing?

Expert Answer:
We know that in insulator the electrons are tightly bound by their shell.
When we rub the insulator with other material, their is a kinetic energy gained by the insulator due to rubbing and hence their shell broke.
Therefore charge started flowing.
In this way insulator get charged while rubbing.
