As a high school student studying electrostatics, I understand that the electric potential at a point closer to a charged particle, is nearly infinite, then why there exist a finite potential difference between two charged objects that are in contact with each other? For example between an electrolyte and its electrodes that are kept close to each other in an electrolytic cell. Can we explain this in typical layman term of work done by an external force in moving a test positive charge from infinity to a point that is at contact with charged object.
