As shown in Fig, a dielectric material of dielectric constant K is insered in half portan between plates of parallel plate capacitor. If its initial capacitance is C, what is the new capacitance ?

A

`1/2 C(K+1)`

B

`1/2C/((1+K))`

C

`1/2((1+K))/C`

D

`C(1+K)`

Text Solution

Verified by Experts

The correct Answer is:
A
`C=(epsilon_(0)A)/d`
`C_(eq)=(epsilon_(0)A//2)/d+(Kepsilon_(0)A//2)/d=(epsilon_(0)A)/(2d) (1+K) =(C(K+1))/2`

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:
