A slab of materail of dielectric constant K has the same area as the plates of a parallel plate capacitor but has thickness d//2 , where d is the separation between the plates. Find the expression for the capacitance when the slab is inserted between the plates.

A slab of material of dielectric constant K has the same area as the plates of a parallel plate capacitor, but has a thickness 3d//4 . Find the ratio of the capacitanace with dielectric inside it to its capacitance without the dielectric.

For changing the capacitance of a given parallel plate capacitor, a dielectric material of dielectric constant K is used, which has the same area is the plates of the capacitor. The thick of the directrie slab is (3)/(4)d, where ‘d’ is the separation between the plates of parallel plate capacite. The new capacitance (C') in terms of original capacitance (C _(0)) is given by the following relation:

Explain why the capacitance of a parallel plate capacitor increases when a dielectric slab is introduced between the plates.

If a dielectric slab of thickness 5 mm and dielectric constant K=6 is introduced between the plates of a parallel plate air capacitor, with plate separation of 8 mm, then its capacitance is

A parallel plate capacitor of plate area A and plate separation d is charged to potential difference V and then the battery is disconnected. A slab of dielectric constant K is then inserted between the plates of the capacitor so as to fill the space between the plates. If Q, E and W denote respectively, the magnitude of charge on each plate, the electric field between the plates (after the slab is inserted), and work done on the system, in question, in the process of inserting the slab, then
