A paralled plate capacitor is made of two square plates of side 'a' , separated by a distance d (dltlta). The lower triangular portion is filled with a dielecttic of dielectric constant K, as shown in the figure. Capacitance of this Capacitor is :

A parallel plate capacitor is made of two square plates of side 'a' , separated by a distance d much less than a. The lower triangular portion is filled with a dielectric of dielectric constant K, as shown in the figure. Capacitance of this Capacitor is : a) (Kin_(0)a^(2))/(2d(K+1)) b) (Kin_(0)a^(2))/(d(K-1)) In K c) (Kin_(0)a^(2))/(d)In K d) (1)/(2)(Kin_(0)a^(2))/(d)

A parallel plate air capacitor has capacitance C. Half of space between the plates is filled with dielectric of dielectric constant K as shown in figure . The new capacitance is C . Then

A parallel plate capacitor has square plates of area A separated by distance ‘d’ between them. It is filled with a dielectric which has a dielectric constant that varies as k(y)=K_0(1+betay) where 'y' is the distance measured from bottom of capacitor. The total capacitance of the system is given by the expression:

A paralle plate air capacitor has capacitance C. Now half of the space is fillel with a dielectric material with dielectric constant K as shown in figure . The new capacitance is C . Then
