In a parallel plate capacitor, the capacitance increases from `4 muF` to `80muF` no introduicng a dielectric medium between the plates. What is the dielectric constant of the medium?

Define dielectric Constant of a medium.

what is the meant by dielectric strength of a medium?

In a parallel plate capacitor, how is the capacitance affected, when without changing the charge, the distance between the plates is doubled.

Derive an expression for the capacitance of a parallel plate capacitor with dielectric as the medium between the plates.

If a parallel plate capacitor of capacitance C is kept connected to a supply voltage V and then to just fill the space, dielectric slab is inserted between the plates. What will be the change in the capacitance the charge, the potential difference, the electric field and the energy stored?

A parallel plate capacitor has a capacitance of 2muF . A slab of dielectric constant 5 is inserted between the plates and the capaitor is charged to 100 V and then isolated. What is the new potential difference, if the dielectric slab is removed?

A parallel plate capacitor has a capacitance of 2muF . A slab of dielectric constant 5 is inserted between the plates and the capaitor is charged to 100 V and then isolated. How much work is required to remove the dielectric slab?

An air capacitor is given a charge of 2muC raising its potential to 200 V. If on inserting a dielectric constant its potential falls to 50V, what is the dielectric constant of the medium?

A parallel plate capacitor has a capacity of 6 muF (Micro farad), with air in between the plates and 60 muF (Micro farad) when dielectric medium is introduced.What is the dielectric Constant (K ) of the medium ?
