When air is replaced by a dielectric medium of constant `K`, the capacity of the condenser.

When air is replaced by a dielectric medium of constant K, the maximum force separated by a distance

The capacity of a capacitor becomes 10 mu F when air between the plates is replaced by a dielectric slab of K = 2. What is the capacity of the condenser with air in between the plates ?

In a parallel plate air capacitor the distance between plates is reduced to one fourth and the space between them is filled with a dielectric medium of constant 2. If the initial capacity of the capacitor is 4muF . then its new capacity is .

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 condenser in which a dielectric of dielectric constant 5 has been used, is C. If the dielectric is replaced by another with dielectric constant 20, the capacity will become

Two condensers of capacity C and 2C are connected in parallel and these are charged upto V volt. If the battery is removed and dielectric medium of constant K is put between the plates of first condenser, then the potential at each condenser is.

The capacity and the energy stored in a parallel plate condenser with air between its plates are respectively C_(0) and W_(0) . If the air is replaced by glass (dielectric constant = 5 ) between the plates, the capacity of the plates and the energy stored in it will respectively be
