Permittivity
 
In electromagnetism, permittivity is the measure of how much resistance is encountered when forming an electric field in a vacuum.
 
Permittivity is a measure of how an electric field affects, and is affected by, a dielectric medium.  
 
Permittivity is determined by the ability of a material to polarize  in response to the field, and thereby reduce the total electric field inside the material.  
 
Thus, permittivity relates to a material's ability to transmit (or "permit") an electric field.
 
It is directly related to electric susceptibility, which is a measure of how easily a dielectric polarizes in response to an electric field.

The constant value ε0 is known as the electric constant or the permittivity of free space.
