In current electricity,one may say that electron flow in a conductor is just like water flow in a river---when water flows from the opposite ends of a ditch,it results in a collision,just like 2 electrons would if they were to move in opposite directions.But you see,water flowing in opposite directions collide or repel because the water has no other space,or volume,to occupy,other than the volume of the river.Had there been any other space,or volume,to occupy,then some of the water would have occupied the extra volume,& the collision would not be so prominent.This is what happens in case of electrons in motion---when 2 electrons,or 2 streams of electrons,flowing in opposite directions meet in a conductor,they have so much of extra space in the wire to occupy(as the volume of all the electrons flowing in the wire is negligible as compared to the volume of the wire), that a collision could easily be prevented.So why does it take place. I may be wrong with my reasoning,but please explain.
