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.

Numerical Problems Based on Definition of Electric Current for Class 12 Physics
Last modified on:4 months agoReading Time:14MinutesElectric Current The physics of charges at rest is called electrostatics or static electricity. We shall now study the motion or dynamics of charges. As the term current implies some sort of motion, so the motion of electric charges constitutes an electric current. Understanding Electric current If two bodies charged to…
