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…

Best Way to Approach Physics Numericals
Last modified on:5 years agoReading Time:13MinutesPhysics is an interesting subject, the presence of problems makes it more. Don’t think any problems to be tough. Don’t be like, yeh problem to bilkul nai hoga mujhse. Rather face the problem. Positive attitude towards problem solving in physics is mandatory. Make sure you understand the concepts clearly. It is an important part in physics.…
