A capacitor of plate area A and separation between plates d is half filled with dielectric of dielectric constant K. What is equivalent capacitance?

A parallel plate capacitor has plates of area A separated by distance ‘d’ between them. It is filled with a dielectric which has dielectric constant that varies as K (y) = k _(0) (1+ alpha y) where ‘y’ is the vertical distance measured from base of the plates. The total capacitance of the system is best given by: (K _(0) is constant)

A parallel plate air capacitor has a capacitance C. When it is half filled with a dielectric of dielectric constant 5, the percentage increase in the capacitance will be

A parallel plate capacitor with air between the plates has a capacitance of 8 pF. The separation between the plates is now reduced by half and the space between them is filled with a medium of dielectric constant K. Calculate the value of the capacitance of the capacitor in the second case.

Show that in parallel plate capacitor, if the medium between the plates of the capacitor is filled with insultaing substance of dielectric contant k, its capacitance increases.

How will the energy stored in a fully charged capacitor chanege when the separation between the plates is doubled and the dielectric medium of constant 4 is introduced between the plates ?

A parallel plate capacitor with air between the plates has capacitance of 9pF. The separation between its plates is 'd'. The space between the plates is now filled with two dielectrics. One of the dielectrics has dielectric constant k_1=3 and thickness d/3 while the other one has dielectric constant k_2=6 and thickness (2d)/(3) . Capacitance of the capacitor is now

What is effect of dielectric on the capacitance of a capacitor?

A parallel plate capacitor with oil between the plates has a capacitance C(dielectric constant of oil is 2). If the oil is removed, then capacitance of the capacitor becomes

For a given potential difference, does a capacitor store more or less charge with a dielectric than it does without a dielectric constant (K) is inserted between the two plates of capacitor. What is the new of charge stored in the capacitor?
