Electrostatic The basic principle of Electrostatics is based on the fact the electric charges attract or repel other charges depending on their relative signs and the law of force is given by Coulomb‘s law. Coulomb’s law states that: The magnitude of the electrostatic force of interaction between two point charges is directly proportional to the … Read more
Electric Discharge In Gases Electrical discharge through gases is studied by using a specially designed glass tube commonly called as a discharge tube. It consists of a cylindrical glass tube having a side tube, and two metallic electrodes one at each end. These electrodes can be connected to the respective terminals of a high tension … Read more
Electromagnetic Wave Electromagnetic Wave are waves composed of undulating electrical fields and magnetic fields. The different kinds of Electromagnetic Waves, such as Light and radio waves, form the electromagnetic spectrum. All electromagnetic waves have the same speed in a vacuum, a speed expressed by the letter c (the speed of light) and equal to about … Read more

Waves A wave can be described as a disturbance that travels through a medium from one location to another location.It is a disturbance or variation that transfers energy progressively from point to point. It may take the form of an elastic deformation, a variation of pressure, electric or magnetic intensity, electric potential, or temperature. When … Read more
