not sure i agree with you.

i was taught linear circuits from a generalized point of view, where you have across variables, and through variables. or as we would have called it at the time, linear network theory. (not to be confused with what most people would associate with networks now, computer networks). within this framework, you have elements that are sources (pretend there are only independent sources for now), and elements that are sinks. by convention, sources have positive across and through variables in the same direction, and on a sink, a positive through variable generates a positive across variable in the opposite direction. for linear electrical circuits, across variable is voltage, and through variable is current. this is conventional current. it is a consequence of a generalized version of a mathematical tool for analyzing linear networks.

now, it just so happened that the proton was assigned positive convention, and the electron negative, before this came about. if electrons had been labelled as positive, conventional current would be electron flow.

i couldn't find the across/through variable stuff on wikipedia (or rather i gave up while i was behind), but here's a couple of things to give you an idea of it.

oh, and looks like google books lets you see it in one of Dorf's books

http://books.google.com/books?id=V-...ge&q=across variable through variable&f=false

i don't know, but i've been told, that the navy used to teach its techs electron flow. and that it made a lot more sense to do that when things ran on tubes.
