Symbol: D
Definition: vector quantity obtained at a given point by adding the electric polarization P to the product of the electric field strength E and the electric constant ε0 :

D = ε0 E + P

NOTE 1 – In vacuum, the electric flux density is at all points equal to the product of the electric field strength and the electric constant:

D = ε0 E

NOTE 2 – The divergence of the electric flux density is equal to the volumic electric charge ρ :

div D = ρ
