Question

write a relation between absolute  and relative electrical permittivity of a medium

Answer 1

Relation between absolute and relative permittivity:

• Absolute permittivity:   Absolute permittivity is well-defined as the measure of permittivity in a vacuum and it is how much resistance is faced when forming an electric field in a vacuum. The absolute permittivity is normally symbolized by ε0. The permittivity of free space - a vacuum - is equivalent to approximately 8.85 x 10-12 Farads / meter (F/m)

• Relative permittivity:   Relative permittivity is well-defined as the permittivity of a given material relative to that of the permittivity of a vacuum. It is normally symbolized by: εr.

And the relationship between these two quantities is  

                                        εr=εs/ε0

Answer 2

Concept

Absolute permittivity is a well defined as the measure of permittivity in a vacuum. Relative permittivity is well defined as the permittivity of a given material relative to that of the permittivity of a vacuum.

To do

Write a relationship between absolute permittivity and relative permittivity.

Explanation

The absolute permittivity is normally symbolised by ohm 0. The permittivity of free spce a vaccumm is equivalent to approximately 8.85*10 tothe power -12 Farads/meter.

The relationship between two are:

ohn *r=es/ohm0
