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.

Last modified on:3 years agoReading Time:20MinutesImportant Derivations for Class 12 Physics Chapter 3 Current Electricity Deduction of Ohm’s law. When a potential difference ‘V’ is applied across a conductor of length ‘l’, the drift velocity in terms of ‘V’ is given by $$ v_d=\frac{e E \tau}{m}=\frac{e V \tau}{m l} $$ If the area of cross-section of…
