I feel like my concept of current is way off. Suppose in a circuit there is a node in which you have a certain amount of charge entering per second. Since charge is quantized, this means you have a certain amount of electrons entering the node per second. Now I would want to say that if, after the node, the wire contains the same elements, then the current would be split exactly. In other words the same current would be flowing in both wires after the node (and their sum would equal the current before the node by Kirchoff's current law). But if there was an odd number of electrons, wouldn't one current be slightly bigger than the other? For example maybe the initial current was 3 electrons. 2 would go one way and 1 the other. Or even how about 1 initially? Then there wouldn't even be a current in the other wire. How can I improve my concept of current to get around these thoughts?
