Question

Define the term " relative permittivity " ​

Answer 1

In simple terms, relative permittivity tells us how well a material can hold an electric charge. A material with a high relative permittivity can hold more electric charge than a material with a low relative permittivity.

Answer 2

Relative permittivity describes the ability to polarize a material subjected to an electrical field.

Step-by-step explanation:

This polarization originates from a number of sources:

- electron cloud displaced relative to nucleus

- relative displacement of charged ions

- alignment of dipoles in electric field

- movement of charge carriers trapped by interfaces in heterogeneous systems

- movement of ionic charges
