Question

What is electric displacement vector?? Give it's formula. ​

Answer 1

Explanation:

ANSWER

★Electric displacement, denoted by D, is the charge per unit area that would be displaced across a layer of conductor placed across an electric field. It is also known as electric flux density.

★Electric displacement is used in the dielectric material to find the response of the materials on the application of an electric field E. In Maxwell’s equation, it appears as a vector field.

★The SI unit of electric displacement is Coulomb per meter square (C m-2).

★The mathematical representation is as follows:

D≡ϵ0E+PD≡ϵ0E+P

★Where,

• ϵ0: Vacuum permittivity
• P: Polarization density
• E: Electric field
• D: Electric displacement field
