How can we maintain a potential difference across a conductor?
(N/A) To maintain a constant potential difference across the ends of a conductor,we need to connect it to a source of electrical energy,such as a cell or a battery.
This source of electromotive force $(emf)$ performs work to move charges,thereby sustaining the flow of current through the conductor.
