What is electric susceptibility?

Electric susceptibility is a measure of how easily a material can be polarized by an electric field. It is a property of dielectric materials and is defined as the ratio of the polarization induced in a material to the strength of the applied electric field.

The electric susceptibility of a material is typically denoted by the symbol χe and is a dimensionless quantity. It is related to the permittivity of the material, which describes how much the electric field is weakened when passing through the material.

Materials with a high electric susceptibility are easily polarized by an electric field and are good insulators. In contrast, materials with a low electric susceptibility are not easily polarized and are good conductors.

Electric susceptibility is an important parameter in the study of dielectric materials and is used to characterize their electrical behavior. It plays a crucial role in the design of capacitors, transformers, and other electrical devices.
