The plates of small size of a parallel plate capacitor are charged as shown. The force on the charged particle of ‘q’ at a distance ‘l’ from the capacitor is : (Assume that the distance between the plates is d<<l) Potential difference between centre and the surface of sphere of radius R having uniform volume [...]

A parallel plate capacitor is filled by a dielectric whose dielectric constant varies with the applies voltage (V) as K = 2 V. A similar capacitor with no dielectric is charged to V0=78 volt.It is then connected to the uncharged capacitor with the dielectric.Find the final voltage on the capacitors Potential difference between centre and [...]

A parallel plate capacitor is to be designed with a voltage rating 1 KV using a material of dielectrical constant 3 and dielectric strength about 107Vm−1. [Dielectric strength is the maximum electric field a material can tolerate without break down, i.e, without starting to conduct electrically through partial ionisation. For safety, we should like the [...]

A solid conducting sphere of radius ‘a’ is surrounded by a thin uncharged concentric conducting shell of radius 2a. A point charge q is placed at a distance 4a from common centre of conducting sphere and shell. The inner sphere is then grounded Potential difference between centre and the surface of sphere of radius R [...]
