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…

Pseudo-Science and Science
Last modified on:4 years agoReading Time:4Minutes Pseudo-Science present itself as science in order to make its claims seem more robust or secure than they actually are. We can call it ‘fake’ science also. Or in other words we can say that pseudo-science is not scientific at all, but they try to create the impression that they…

Virtual Reality
Last modified on:4 years agoReading Time:8Minutes Virtual reality: What is it? A simulated 3D environment called virtual reality allows users to explore and interact with a virtual environment in a fashion that simulates reality as it is experienced by the users’ senses. Although the environment is built using computer hardware and software, users may also need…
