Permittivity

Permittivity is a measure of how easily a material allows an electric field to pass through it. Think of it as the material's ability to store electrical energy when exposed to an electric field. Higher permittivity means the material can store more electric energy for a given electric field strength. This property influences how capacitors work and affects the behavior of electric fields in different materials. In essence, permittivity describes how a material responds to electric forces, shaping the way they interact with electricity and electromagnetic signals.
