Question

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

Answer 1

$\huge\mathbb{ \underline \red{Answer:-}}$

Electric Displacement Vector :-

✓ is also called as Dielectric Displacement pr electric flux density.

✓is denoted by 'D'.

✓is the charge per unit area that would be displaced across an electric field.

Formula for Electronic Displacement Vector :-

D = E + 4πP

The above formula is in cgs unit systems.

Answer 2

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.

Electric displacement D = ε0E + P. In this case, ε0 is vacuum permittivity, E is electric field, and P is polarization density.
