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.

Alternating Current
Last modified on:3 years agoReading Time:24Minutes What is Alternating Current (A.C.)? Alternating Current (AC) is an electrical current that periodically reverses direction in a circuit. Unlike Direct Current (DC), which flows only in one direction, AC constantly changes its polarity and magnitude over time. Explanation: In an AC circuit, electrons periodically switch direction, moving back and…
