Permittivity, Relative Permittivity And Dielectric Constant | Electrical4U

A SIMPLE explanation of permittivity (also known as relative permittivity or Dielectric Constant. If you want to learn more about permittivity, you can learn more at: https://www.electrical4u.com/permittivity-and-relative-permittivity-or-dielectric-constant/ Relative permittivity is defined as the ratio of the actual or absolute permittivity of a medium to the absolute permittivity of a vacuum. The permittivity of a medium is expressed as ε. This ratio is 1.0006 for air. That means the relative permittivity of air is 1.0006. The electrostatic force acting between nearby electrically charged bodies is inversely proportional to the permittivity of the medium. Hence, the relative permittivity of any medium is defined as the ratio of force acting between nearby electrically charged bodies in the vacuum to the force acting between the same bodies separated by the same distance in the medium.
