The electric flux through a closed surface is NOTE: surface.a vast number of tiny pieces, pieces that now cover a closedThe electric flux is still the summation of the fluxes through A closed surface has a distinct inside and outside. The area vector dA is defined to always point toward the outside. This removes an ambiguity that was present for a single surface, where dA could point to either side.
