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.

Tyndall effect
Last modified on:3 years agoReading Time:8MinutesWhat is Tyndall effect? The Tyndall effect, also known as Tyndall scattering, is a phenomenon observed when light is scattered by colloidal particles or small particles suspended in a transparent medium. This effect is named after the 19th-century British physicist John Tyndall, who extensively studied the scattering of light by various…
