The considerations are quite similar to those encountered in the development of boundary conditions on the electric field intensity (\({\bf E}\)) in Section 5.17, so the reader may find it useful to review that section before attempting this section. . This section also assumes familiarity with ...

For that reason, one usually refers to the “flux of the electric field through a surface”. This is illustrated in Figure 17.1.1 17.1. 1 for a uniform horizontal electric field, and a flat surface, whose normal vector, A A →, is shown. If the surface is perpendicular to the field (left panel), and the field vector is thus parallel to the ...Electric Flux Density. The number of electric field lines or electric lines of force flowing perpendicularly through a unit surface area is called electric flux density. Electric flux density is represented as D, and its formula is D=ϵE. Electric flux is measured in Coulombs C, and surface area is measured in square meters ( m2 m 2 ).
