Question

What is relative permittivity

Answer 1

Permittivity is a property of a dielectric medium that determines how well it transmits an electric field. It is determined by how much the medium polarizes in response to an electric field.

Hope this helps:

Answer 2

Relative permittivity is the factor by which the electric field between the charges is decreased relative to vacuum. Likewise, relative permittivity is the ratio of the capacitance of a capacitor using that material as a dielectric, compared with a similar capacitor that has vacuum as its dielectric.
