If K is the dielectric constant of the medium. A is area of insulated charged plates and d is the distance between two plates of parallel plate condenser then its capacity in CGS unit is

The capacity of a parallel plate condenser is C. When the distance between the plates is halved, its capacity is

Two identical condensers M and N are connected in series with a battery. The space between the plates of M is completely filled with a dielectric medium of dielectric constant 8 and a copper plate of thickness d/2 is introduced between the plates of N. (d is the distance between the plates). Then potential differences across M and N are, respectively, in the ratio

The capacity of a parallel plate condenser without any dielectric is C. If the distance between the plates is doubled and the space between the plates is filled with a substance of dielectric constant 3, the capacity of the condenser becomes:

The capacity of a parallel plate condenser without any dielectric is C. If the distance between the plates is doubled and the space between the plates is filled with a substance of dielectric constant 3, the capacity of the condenser becomes:
