Question

define relative permittivity and its s.i unit​

Answer 1

Explanation:

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). ... By definition, a perfect vacuum has a relative permittivity of exactly 1.

Answer 2

Answer:

Explanation:

It is the property of every material, which measures the opposition offered against the formation of an electric field. Represented by the Greek alphabet ϵ. It tells the number of charges required to generate one unit of electric flux in the given medium. Following is the table for its mathematical form and SI unit:

Permittivity= electric displacement/electric field intensity

SI unit of permittivity:-Faraday/meter
