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…

PROPERTIES OF CHARGE
Last modified on:5 years agoReading Time:4MinutesSPECIFIC PROPERTIES OF CHARGE • Charge is a scalar quantity : It represents excess or deficiency of electrons. • Charge is transferable : If a charged body is put in contact with an another body, then charge can be transferred to another body. • Charge is always associated with massCharge cannot…

Charging of a body
Last modified on:5 years agoReading Time:5MinutesCharging of a body Charging can be done by two methods; 1. Conduction 2. Induction Ordinarily, matter contains equal number of protons and electrons. A body can be charged by transfer of electrons or redistribution of electrons. Charging by conductionThe process of charging from an already charged body can happen either…

Electric Charge
Last modified on:5 years agoReading Time:7MinutesELECTRIC CHARGECharge is the property associated with matter due to which it produces and experiences electrical and magnetic effects. The excess or deficiency of electrons in a body gives the concept of charge. Types of charge :(i) Positive charge : It is the deficiency of electrons as compared to proton(i) Negative…
