# How to Calculate and Solve for Dielectric Constant | Electrical Properties

The dielectric constant is illustrated by the image below. To compute for dielectric constant, two essential parameters are needed and these parameters are Permittivity of Dielectric Material (ε) and Permittivity of Vacuum (εo).

The formula for calculating the dielectric constant:

εr = ε/εo

Where:

εr = Dielectric Constant
ε = Permittivity of Dielectric Material
εo = Permittivity of Vacuum

Given an example;
Find the dielectric constant when the permittivity of dielectric material is 36 and the permittivity of vacuum is 9.

This implies that;

ε = Permittivity of Dielectric Material = 36
εo = Permittivity of Vacuum = 9

εr = ε / εo
εr = 36 / 9
εr = 4

Therefore, the dielectric constant is 4.

Calculating the Permittivity of Dielectric Material when the Dielectric Constant and the Permittivity of Vacuum is Given.

ε = εro)

Where:

ε = Permittivity of Dielectric Material
εr = Dielectric Constant
εo = Permittivity of Vacuum

Let’s solve an example;
Find the permittivity of dielectric material when the dielectric constant is 14 and the permittivity of vacuum is 17.

This implies that;

εr = Dielectric Constant = 14
εo = Permittivity of Vacuum = 17

ε = εro)
ε = 14 (17)
ε = 238

Therefore, the permittivity of dielectric material is 238.

Calculating the Permittivity of Vacuum when the Dielectric Constant and the Permittivity of Dielectric Material is Given.

εo = ε / εr

Where:

εo = Permittivity of Vacuum
εr = Dielectric Constant
ε = Permittivity of Dielectric Material

Let’s solve an example;
Find the permittivity of vacuum when the dielectric constant is 24 and the permittivity of dielectric material is 48.

This implies that;

εr = Dielectric Constant = 24
ε = Permittivity of Dielectric Material = 48

εo = ε / εr
εo = 48 / 24
εo = 2

Therefore, the permittivity of vacuum is 2.
