Right the other thing that always weirded me out when I was a student is you go from the top diagram which almost has a almost like a Y you have 1 coming in and 1 coming at the top and the emitter coming out and then at the bottom equivalent circuit we sort of split the branches so they look like they are coming in 2 separate paths to the emitter but of course all of bottom wires are all shorted together. &amp;gt;&amp;gt;:
