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.

Our Environment
Last modified on:5 years agoReading Time:11Minutes• Everything that surrounds us is environment. It includes both living (biotic) and non-living (abiotic) components. • Interaction between these biotic and abiotic components form an ecosystem. • In an ecosystem living components depend on each other for their food which give rise to food chains and food webs in nature.…
