Define .dielectric constant. of a medium. Briefly explain why the capacitance of a parallel plate capacitro increases, on introducing a dielectric medium between the plates.

Compare the capacitance of a parallel plate capacitor with and without the dielectric medium.

How will you increase the capacitance of a parallel plate capacitor ?

How does electrical capacitance of a parallel plate capacitor depend on the distance between the plates ?

What is the effect of the presence of a dielectric medium on Capacitance of a parallel plate capacitor.

While a capacitor remains connected to a battery, a dielectric slab is slipped between the plates. Then

A parallel plate capacitor has two plates of dimensions 10 cm xx 7 cm separated by a distance of 0.7 mm. A glass plate of thickness 0.4 mm (dielectric constant = 6) and another dielectric medium of thickness 0.3 mm (dielectric constant = 2.5) are placed between the plates of the capacitor. Calculate the capacitance of the capacitor before and after introduction of the dielectric media.

Compare the electrical capacitance of a spherical capacitor with and without the presence of dielectric medium.

A slab of material of dielectric constant K has the same area as the plates of a parallel-plate capacitor but has a thickness (3/4)d, where d is the separation of the plates. How is the capacitance changed when the slab is inserted between the plates?
