				   What is this permittivity of free space or epsilon not

6 years ago


Answers : (1)


Dear Sunil

In electromagnetism, permittivity is the measure of how much resistance is encountered when forming an electric field in a medium. In other words, 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.

its value is  8.85418782 × 10-12 m-3 kg-1 s4 A2  

or 8.85… × 10−12 F/m

All the best.
