The image of dielectric displacement is shown above.

To compute for dielectric displacement, two essential parameters are needed and these parameters are **Permittivity of Vacuum (ε _{o})** and

**Electric Field Intensity (E).**

The formula for calculating the dielectric displacement;

D_{o} = ε_{o}E

Where:

D_{o} = Dielectric Displacement

ε_{o} = Permittivity of Vacuum

E = Electric Field Intensity

Given an example;

Find the dielectric displacement when the permittivity of vacuum is 28 and the electric field intensity is 4.

This implies that;

ε_{o} = Permittivity of Vacuum = 28

E = Electric Field Intensity = 4

D_{o} = ε_{o}E

D_{o} = (28)(4)

D_{o} = 112

Therefore, the **dielectric displacement **is **112 C/m².**

**Calculating the Permittivity of Vacuum when the Dielectric Displacement and the Electric Field Intensity is Given.**

ε_{o} = D_{o}E

Where:

ε_{o} = Permittivity of Vacuum

D_{o} = Dielectric Displacement

E = Electric Field Intensity

Let’s solve an example;

Find the permittivity of vacuum when the dielectric displacement is 4 and the electric field intensity is 6.

This implies that;

D_{o} = Dielectric Displacement = 4

E = Electric Field Intensity = 6

ε_{o} = D_{o}E

ε_{o} = 4(6)

ε_{o} = 24

Therefore, the **permittivity of vacuum **is **24.**
