Question

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

Answer 1

Answer:

Electric displacement, auxiliary electric field or electric vector that represents that aspect of an electric field associated solely with the presence of separated free electric charges, purposely excluding the contribution of any electric charges bound together in neutral atoms or molecules.

Explanation:

Electric displacement D = ε0E + P.

★ 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:

$\bold{D = ϵ0E + P}$

★Where,

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