what is dielectric constant?
Answers
a quantity measuring the ability of a substance to store electrical energy in an electric field.for example, The dielectric constant k is the relative permittivity of a dielectric material. It is an important parameter in characterizing capacitors. It is unfortunate that the same symbol k is often used for Coulomb's constant, so one must be careful of this possible confusion.

DIELECTRIC CONSTANT:-
The dielectric constant or relative permittivity of a medium may be defined as the ratio of the force between two charges placed some distance apart in free space to the force between the same two charges when they are placed at the same distance apart in the given medium .
formula:-
k(dielectric constant)=Fvac/Fmed
