Question

Define the term ‘electric polarisation’ of a dielectric medium. Write its
S.I. unit.

Answer 1

More specifically, permittivity describes the amount of charge needed to generate one unit of electric flux in a particular medium. ... Permittivity is the measure of a material's ability to store an electric field in the polarization of the medium. The SI unit for permittivity is farad per meter (F/m or F. · m−1).
