a capacitor is charged by connecting it to a DC source (Figure 19-3), electrons are removed from the plate connected to the positive battery terminal and are deposited on the plate connected to the negative terminal. This flow of current continues until a voltage equal to the battery voltage is established across the plates of the capacitor (Figure 19-4).
In a capacitor, the plates are only charged at the interface facing the other plate. That is because the "right" way to see this problem is as a polarized piece of metal where the two polarized parts are put facing one another. In principle, each charge density generates a field which is $sigma/2 epsilon$.
