what do you mean by dielectric constant.
Answers
Answer:
Dielectric constant (ϵr) is defined as the ratio of the electric permeability of the material to the electric permeability of free space (i.e., vacuum) and its value can derived from a simplified capacitor model.
Explanation:
What is Dielectric Constant?
The dielectric constant of a substance can be defined as:
The ratio of the permittivity of the substance to the permittivity of the free space
It expresses the extent to which a material can hold electric flux in it.
Dielectric Constant Formula
It is mathematically expressed as:
κ=εε0Where,
κ is the dielectric constant
is the permittivity of the substance
0 is the permittivity of the free space
Dielectric Constant Units
As it is the ratio of two like entities, it is a unitless, dimensionless quantity.
Dielectric Constant Symbol
The relative permittivity of a dielectric substance is also called a Dielectric Constant, expressed using the Greek letter kappa ‘κ’.
