Relative Permittivity Calculator

Formula

The formula to calculate the relative permittivity (εr) is:

\[ \epsilon_r = \frac{C}{C_0} \]

Where:

Relative Permittivity: Also known as the dielectric constant, it is a measure of how much a material can hold an electric charge compared to a vacuum. It indicates how much the electric field is reduced inside the material compared to a vacuum. A higher relative permittivity means the material can store more charge at a given voltage. This property is crucial in the design of capacitors and for understanding the electrical properties of materials.

Let's say the capacitance of the material (C) is 5 farads and the capacitance in a vacuum (C₀) is 1 farad. Using the formula:

\[ \epsilon_r = \frac{5}{1} \]

We get:

\[ \epsilon_r = 5 \]

So, the relative permittivity is 5.
