Where does the voltage drop of a capacitor happen? My answer would be that It produces an electric field the opposes the field of the battery along the wires. So it is continuous lose to the capacitor which stores this energy in it. Another question related to this, When a positive charge hits one terminal of a capacitor another fires away from the other. T I can see why this happens by saying that the current in and out must be equal because of KCL. But can this be related to Newton cradle? Where one only can go out to conserve momentum and energy? There is no voltage drop when a charge "move" from one side to another.
