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.

Charging by Contact
Last modified on:4 years agoReading Time:2Minutes Charging by Contact When a negatively charged ebonite rod is rubbed on a metal object, such as a sphere, some of the excess electrons from the rod are transferred to the sphere. Once the electrons are on the metal sphere, where they can move readily, they repel one another and…

Charging by Rubbing
Last modified on:4 years agoReading Time:3Minutes Charging by Rubbing The simplest way to charge certain bodies is to rub them against each other. When a glass rod is rubbed with a silk cloth, the glass rod acquires some positive charge and the silk cloth acquires negative charge by the same amount. The explanation of appearance of…

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…
