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.

Reynolds Number
Last modified on:3 years agoReading Time:10MinutesWhat is Reynolds Number? The Reynolds number (Re) is a dimensionless parameter used in fluid mechanics to characterize the flow of a fluid (liquid or gas) around an object or through a conduit. It relates the inertial forces to the viscous forces in the fluid and helps determine the type of…

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,…
