Let me put it this way: never have I heard an explanation in terms of classical mechanics. In my intuition, the billiard ball model of physics makes perfect sense. But a current taking the path of least resistance really seems like it "knows" the best way. And it's amazing.
- tannercollin 9y agoThat's a misconception. Electricity takes ALL paths in amounts proportional to each path's conductance. If you have a 1000 Ω path and a 10 Ω path (in parallel), current will go through both paths. However, much more current will go through the 10 Ω path. The current through each path ends up being the voltage applied across the path, divided by its resistance.
- planteen 9y agoYep. Came here to say exactly this (electricity takes all paths) and then saw your reply.
