A parallel plate capacitor filled with a dielectric of relative permittivity 5 between its plates is charged to acquire an energy E and isolated. If the dielectric is replaced by another of relative permittivity 2, its energy becomes

A parallel plate capacitor is filled with dielectrics as shown in Fig. What is its capacitance ?

A parallel plate capacitor with a dielectric slab with dielectric constant k= 3 filling the space between the plates is charged to potential V and isolated. Then the dielectric slab is drawn out and another dielectric slab of equal thickness but dielectric constant k'= 2 is introduced between the plates. The ratio of the energy stored in the capacitor later to that initially is:

When a parallel plate capacitor is filled with wax after separation between plates is doubled, its capacitance becomes twice. What is the dielectric constant of wax?

When a parallel plate capacitor is filled with wax after separation between plates is doubled, its capacitance becomes twice. What is the dielectric constant of wax?

In a parallel plate capacitor, if the intervening medium of permittivity & between the plates is replaced by another medium of permittivity epsi/2 , then its capacitance is

On placing a dielectric slab between the plates of an isolated charged condenser its -

The figure shows two identical parallel plate capacitors connected to a battery with the switch S closed. The switch is now opened and the free space between the plates of the capacitors is filled with a dielectric of dielectric constant(or relative permittivity) 3. Find the ratio of the total electrostatic energy stored in both capacitors before and after the introduction of the dielectric.
