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…

Electric Field Due to a Point Charge
Last modified on:3 years agoReading Time:1MinuteElectric Field Due to a Point Charge The electric field produced by a point charge q can be obtained in general terms from Coulomb’s law.First note that the magnitude of the force exerted by the charge q on a test charge q0 is then divide this value by q0 to obtain…

Electric Field Due to a Charged Ring
Last modified on:3 years agoReading Time:4MinutesElectric Field Due to a Charged Ring A conducting ring of radius R has a total charge q uniformly distributed over its circumference. We are interested in finding the electric field at point P that lies on the axis of the ring at a distance x from its centre. We divide…

Conservation Laws in Physics – Definitions, Applications, Examples
Last modified on:3 years agoReading Time:14MinutesConservation Laws in Physics – Definitions, Applications, Examples Conservation laws are fundamental principles of physics that state that certain physical quantities remain constant in a system, even as the system evolves or undergoes transformations. In other words, these laws describe how some properties of a system cannot be created or destroyed,…

Father of Sets – Georg Cantor
Last modified on:3 years agoReading Time:7MinutesFather of Sets – Georg Cantor The “Father of Sets” is Georg Cantor, a German mathematician who is widely credited with developing the theory of sets, which is a fundamental concept in modern mathematics. Cantor was born in 1845 and spent most of his life working in Germany, where he taught…
