Talk:Circuit Theory/Circuit Basics/Open and Closed Circuits

I just edited the section on closed circuits; here's what it said before:

''A closed circuit, or a "Short circuit" is simply another name for a wire. A closed circuit is a section of      the circuit that has no significant resistance. If the theoretical resistance goes to zero, ohms law states that any voltage will cause the current flow to approach infinity.''

''Any time this wikibook mentions that voltage or current go to infinity, the reader should keep in mind that the physical circuit will fail long before the value actually reaches infinity. Such failure can cause damage to the circuit, and possibly even harm to people nearby. In colloquial use, it is not unheard of to say that the circuit "explodes" at this point.''

Now, how I understand it, any completed circuit with a flowing charge is "closed" but you wouldn't call any working circuit a "short circuit". Also, I've been told despite what most books say, current doesn't flow, charge does; this makes a lot more sense, as current is charge/time which is a speed measurement, not an object quantity.
