Question

what is the physical significance of the relative permittivity of a material placed between two plates of capacitor?

Answer 1

Answer:

If a material with a high relative permittivity is placed in an electric field, the magnitude of that field will be measurably reduced within the volume of the dielectric. This fact is commonly used to increase the capacitance of a particular capacitor design.

Answer 2

Answer : Physical significance of the relative permittivity of a material placed between two plates of capacitor is defines as when a material with a high relative permittivity is placed in an electric field, the magnitude of that field will be measurably reduced within the volume of the dielectric. This fact is commonly used to increase the capacitance of a particular capacitor design.

Explanation:

• In electronics, the physical material placed between two plates is considered a dielectric. This is typically an insulating/non-conductive material. These two plates and this dielectric material can be considered a capacitor.

• Permittivity is a constant of proportionality that exists between electric displacement and electric field intensity.

• Dielectric Permittivity is a physical property of a dielectric material that characterizes the degree of electrical polarization a material experiences under the influence of an external electric field. This is how a capacitor work.

• A larger relative permittivity means that the material is polarizable. When the capacitor is charged, the material becomes polarized, increasing the electric field within without an increase in the applied voltage across the plates. And this means that the capacitance of the capacitor is increased.

Hence Physical significance of relative permittivity of a material placed between two plates of capacitor is defines as larger relative permittivity means that capacitance of the capacitor is increased.
