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…

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…
