When you use Maxwell's equations to determine electric and magnetic fields, a lot depends on making the "right" choice for the integration path. What happens if you choose the "wrong" path? Do the equations still hold? Consider a parallel-plate capacitor with circular plates, but use a rectangular integration path that has two sides parallel to the plates and two sides perpendicular to them, as in Figure P30.32. What do you get?
