Electromagnetic Waves

Now consider another surface with the same boundary and a pot like surface and has its bottom between the plates of the capacitor (fig i) and another surface like a tiffin box (fig ii) (all three are of the same perimeter). Applying ACL to them, we find that the left side of the equation has not changed but the right side becomes 0 as no current passes through the surface. Therefore, we conclude a term must be missing from ACL. to find this missing term, consider the electric field passing between the two plates. Let the charge on the plates be Q, Area A then the magnitude of field between the fields-
