Permittivity of a Material
- The permittivity is the property of the material which shows the development of an electric field in the presence of an external electric field.
- In other words, It is the ability of the material to develop the electric field in the presence of an external electric field.
- It is represented by the symbol ε.
- It is expressed as the ratio of the electric displacement to the electric field intensity.
- The SI unit of permittivity is farad per meter (F/m).
- The vacuum has the lowest possible permittivity which is approximately 8.85 X 10-12 Farad/meter.
