What is the permittivity of a medium? Definition of Permittivity The approximate value for permittivity is 8.85 X 10-12 Faraday/meter, which is found in vacuum medium. The permittivity measures the number of charges needed for generating a unit of electric flux in a specific channel. What is electric intensity in physics? What is Electric Field […]
