Does the branch current method outlined in chapter 10 use electron flow or conventional flow when mapping out the direction of the currents? You would think electron flow because the text states it uses electron flow but I found evidence that suggest otherwise. Using a circuit simulator (http://www.alternate-energy.net/aps/circuit_simulator05.html) to simulate a few circuits, it seems that all current directions are under conventional flow when using this method. If someone could clarify this matter for me I would appreciate it.
