How does permittivity affect electric field intensity?

Answer 1

The concept of permittivity describes how a material medium is either affected or is affected by an electric field.

If the electric field in a space is E is vacuum and we put a a material medium with permittivity #epsilon# in that region, the electric field reduces by a factor of #epsilon/(epsilon""_0)# which is equal to the dielectric constant #K""_D# of the medium.

A decrease in the net electric field is observed as a result of the material medium's presence, which partially cancels the effect of the electric field's polarized field in the medium.

Permittivity affects electric field intensity by determining how easily electric field lines can pass through a material. A material with high permittivity allows electric field lines to penetrate easily, resulting in a weaker electric field intensity, while a material with low permittivity restricts the penetration of electric field lines, leading to a stronger electric field intensity.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
