1) Let's say you have two items that lie next to eachother sharing a surface. A is 10 degrees C, and B is -10 degrees C. If this system sits there until A is down to perhaps 5 degrees C, does that automatically mean that B is now -5 degrees C? If not, why is it so? It would probably depend on whether or not both A and B were made of the same material? 2) One often says that electricity takes the way of least resistance, but if a wire splits up to form let's say 5 parallel wires of varying resistance, doesn't the electricity need to flow through all 5 in order to find out which one is the easiest way? And if it then had some kind of "intelligence" it could - based on that - then choose the way of least resistance?
