Do relative permittivity and dielectric constant of a medium imply different physical qantities?
Relative permittivity and dielectric constant are often used interchangeably, but they can imply different contexts. Relative permittivity (ε_r) is a dimensionless measure of a material's ability to store electrical energy in an electric field, relative to the vacuum. The term "dielectric constant" traditionally refers to this same quantity, but it can sometimes be used more loosely to describe the material's overall insulating properties. Thus, while they represent similar concepts, the terminology can depend on the specific physical context being discussed.

Dielectric constant of metal is?
The dielectric constant varies, depending on the material.
Is relative dielectric constant dimensionless?
Correct: it is a dimensionless number.
What is constant k?
There are a number of K constants:1) k, the spring constant in Hooke's law relating deformation (strain) and force applied (stress) to a material body.2) k or kB, the Boltzmann constant, the physical constant relating energy and temperature at the particle level.3) K is a thermodynamic chemical equilibrium constant.4) Coulomb's constant k e is used in measuring electrostatic interaction between electrically charged particles. It comes from three other constants: the speed of light c 0 , magnetic permeability μ 0 , and electric permittivity ε 0.5) κ (kappa), in semiconductor manufacturing, means a low-κ dielectric: a material with a small dielectric constant relative to silicon dioxide.
Difference between permeability constant and permittivity constant?
Permittivity is the measure of access of electric field in any medium while the other is the same of magnetic field in any medium. This is because of symmetry between the electric field and magnetic field that they depend on the medium in which they exist. The both have different units and different relations with their respective fields. Here is a relation between the both for those who are interested in MODERN PHYSICS but it has nothing to do in electromagnetics alone. 1/( ε0 µ0) =c^2 This answer has been given by Muhammad Saad Nawaz
What is dk measurement?
DK measurement is the measurement of the relative dielectric constant of liquids and solid material. It is a measure of permeability.
