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.

Conductors and Insulators
Last modified on:4 years agoReading Time:2MinutesConductors and Insulators Solids are mainly classified into two groups, conductors and insulators. In conductors, electric charges are free to move from one place to another, whereas in insulators they are tightly bound to their respective atoms. In an uncharged body, there are equal number of positive and negative charges. The…

ICSE Class 10 Chemistry Chapter Tests (Editable) – Board Pattern | Question Papers & Marking Scheme
Last modified on:3 months agoReading Time:10MinutesTeaching concepts is only half the battle; testing them is where the real results happen. But for busy teachers, creating a balanced, Board-standard test paper for every single chapter (Force, Light, Electricity, etc.) is a grueling task. Creating a Chemistry test paper is physically draining. Typing balanced equations, getting the subscripts…
