Electrostatics

Electric potential In electricity, the potential is a very important and significant term. If two charged bodies are connected by a conducting wire, charges may…

Electric flux: The number of electric lines of force or field lines passing through a plane or surface is called electric flux. It is denoted…

Electric field intensity or Electric intensity Everywhere in the electric field, its influence is not same. The electric force which a test charge experiences near…

Uniform electric field: If the magnitude and direction of the electric field are same everywhere, then the field is called uniform electric field [Figure]. Example:…

Before discussing electric field let define a test charge., “An imaginary charge of exceedingly small magnitude whose presence does not affect other charges i.e. does…

Superposition principle of electric force In order to find the resultant force, all charges are considered separately with that particular charge as if all other…

Electric force In an electric field there always exists a force on a charge. If the charge is positive then the force acts along the…

Condition for obtaining clear and broad interference bands (i) The screen should be as far away from the source as possible. (ii) The wavelength of…

Huygen’s principle helps us to locate the new position and shape of the wavefront at any instant, knowing its position and shape at any previous…

When a stone is dropped in a still water, waves spread out along the surface of water in all directions with same velocity. Every particle…
