A note on circuit drawing conventions.
In olden days when one wire crossed over another we used to build a little hump-backed bridge to give it a smooth journey. If 2 or more wires met then they were connected. Then the dots got in on the act and the bridges were redundant. Every T junction had a little dot to say it was connected. The problem was with crossroads. Connected ot not? A dot says connected but is easily missed so the modern convention is that a crossroads is never connected with a dot. If you're tempted to doy it, move the wires away from each other. Just like plumbing really where you don't usually have 4 way "X" joints and use a pair of "T".
