how do wires work?

Question

I learnt in one of my classes that “current flows in the path of least resistance” but how does the current know which path is least resistant?

Answer 1

It doesn’t “know” basically it attempts to go down every possible path and the other electrons queue up behind , when one moves another jumps in behind it and so on as the current starts to flow in a similar way how lightning strikes make it to the ground.
