Dielectric Constant Or Relative Electical Permittivity

When the charges are isolated in medium other then vacuum, for is give by
 Where, ε is called absolute electrical Permittivity of medium. The ratio which is given below is called relative electrical Permittivity of medium.
 The value of K depends only on the nature of medium.
