What condition is necessary for the sustained flow of water in a pipe? What analogous condition is necessary for the sustained flow of charge in a wire?
Solution 2RQ Step 1: Water will flow naturally from a region having high potential to a region having low potential. Or we can refer it as the “pressure difference” between two points. So, for a sustained flow of water from one place to another, we need a sustaining pressure difference or potential energy difference between the start point and end point of the flowing water.
