Without potential difference, current can flow or not give reason?
Without potential difference, current can not flow because we know that an electric current flows between two points due to the potential difference between them. Thus, as long as the potential difference is maintained between the two points, the electric current keeps flowing continuously. And the easiest way to maintain a potential difference between the two ends of a conductor is to connect the conductor between the terminal or poles of a cell or a battery.
When the two charged bodies at different potential are connected by a metal wire, it is found that the flow of charge takes place from the body at higher potential to another body at a lower potential.
This flow of electric charges in a conductor (metal wire) is called electric current.
The poles or terminals with relatively more electrons is said to have negative polarity, the other is assigned positive polarity.
The difference measured between the two potentials is called potential difference or voltage.
