Dielectric constant of the medium is the ratio of
the electrostatic force of interaction between two given point charges
held certain distance apart in vacuum/air to the force of interaction
between the same two charges held the same distance apart in the
material medium. F0/Fm=e/e0=K……………………………………………(from Coloumb’s law).
Physical
significance of dielectric constant is the resistivity to stop the
current or conduct electricity through material but induces charge on it
in electrostatic.
The electrical primittivity
is a quantity which is a measure of how much resistance the electric
lines of force encounter while forming an electric field in a particular
medium.
It is denoted by e.
