How to Calculate and Solve for Polarization of Dielectric Medium | Electrical Properties

The image of polarization of dielectric medium is shown below.

To compute for polarization of dielectric medium, three essential parameters are needed and these parameters are Permittivity of Vacuum (εo), Dielectric Constant (εr) and Electric Field Intensity (E).

The formula for calculating polarization of dielectric medium:

P = εor – 1)E

Where:

P = Polarization of a Dielectric Medium
εo = Permittivity of Vacuum
εr = Dielectric Constant
E = Electric Field Intensity

Let’s solve an example;
Find the polarization of dielectric medium when the permittivity of vacuum is 12, the dielectric constant is 6 and the electric field intensity is 4.

This implies that;

εo = Permittivity of Vacuum = 12
εr = Dielectric Constant = 6
E = Electric Field Intensity = 4

P = εor – 1)E
P = (12)(6 – 1)(4)
P = (12)(5)(4)
P = 240

Therefore, the polarization of dielectric medium is 240 C/m².

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.
