โก Understand How Materials Interact with Electric Fields!
When you’re dealing with electrical components, antennas, capacitors, or even insulators, one property really matters: relative permittivity.
A Relative Permittivity Calculator helps you quickly determine this important property without complex equations! ๐
Letโs break it down in simple terms.

๐ข How to Use the Calculator
Itโs super simple:
Enter the Measured Capacitance with the Material
This is typically measured using a capacitance meter.
Enter the Capacitance without the Material
This could be the theoretical capacitance in vacuum or measured without the dielectric.
Calculate
The calculator divides the two values and gives you the relative permittivity.
๐งฎ Relative Permittivity Calculator
โ๏ธ Example
Letโs say:
- Measured Capacitance with Dielectric = 12 pF
- Capacitance in Vacuum = 8 pF
Using the formula:
Relative Permittivity (ฮตแตฃ) = 12 รท 8 = 1.5
๐ The relative permittivity is 1.5
That means the material increases capacitance by 50% compared to vacuum!
๐ What Is Relative Permittivity?
Relative permittivity (also known as dielectric constant) measures how much a material can “store” electrical energy compared to a vacuum.
In short:
- A higher relative permittivity = better at storing electrical energy.
- A lower relative permittivity = closer to the behavior of free space (vacuum).
The symbol for relative permittivity is ฮตแตฃ.
The formula is:
ฮตแตฃ = (Capacitance with Dielectric) รท (Capacitance in Vacuum)
Where:
- Capacitance with Dielectric (Cโ) = Capacitance when the material is used
- Capacitance in Vacuum (Cโ) = Capacitance without any material (just air or vacuum)
๐ฏ Why Use a Relative Permittivity Calculator?
Hereโs why engineers, scientists, and hobbyists use it:
- โ Design better capacitors and RF circuits
- โ Understand how materials affect electric fields
- โ Choose the right materials for insulation
- โ Improve antenna and sensor performance
Instead of manually solving complex formulas, you just input two numbers โ and get instant results!
