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 (ε _{o}).**

The formula for calculating the dielectric constant:

ε_{r} = ^{ε}/_{εo}

Where:

ε_{r} = Dielectric Constant

ε = Permittivity of Dielectric Material

ε_{o} = 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

ε_{o} = Permittivity of Vacuum = 9

ε_{r} = ^{ε} / _{ε}_{o}

ε_{r} = ^{36} / _{9
}ε_{r} = 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 = ε_{r} (ε_{o})

Where:

ε = Permittivity of Dielectric Material

ε_{r} = Dielectric Constant

ε_{o} = 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;

ε_{r} = Dielectric Constant = 14

ε_{o} = Permittivity of Vacuum = 17

ε = ε_{r} (ε_{o})

ε = 14 (17)

ε = 238

Therefore, the **permittivity of dielectric material **is **238.**
