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.

Frictional Electricity
Last modified on:3 years agoReading Time:10Minutes What is frictional electricity? Frictional electricity, also known as static electricity, is the type of electricity that results from the friction or rubbing of two objects together. When two objects are rubbed against each other, the friction between them can cause the transfer of electrons from one object to the…

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…

Terminal Velocity
Last modified on:3 years agoReading Time:13Minutes What is Terminal Velocity? Terminal velocity is the constant maximum speed reached by an object in free fall or falling through a fluid (such as air or water) when the force of air resistance or fluid resistance becomes equal in magnitude and opposite in direction to the force of gravity…
