In a complex resistive mesh (grid), 2 points are chosen for applying a voltage source. Now there are many paths the current can take from A to B. And there is an equivalent resistance computed as well. But how to calculate the least resistive path? I.e. The path along which when traversed, the sum of resistances that we come across in that very path is the least. How to find out this path? The generality of working of my designed circuit is based on this principle. Thanks in advance!
