Okay I have one thing to ask about a coulomb, but I need to be REAL careful to state that this question is not not trying to try in the analogy of the water bit people like to use in electronics so often.
BUT... Wouldn't a coulomb be kind of like just cup of water. a cup of water is just a set amount that we talk about to help understand a quantity of water not what the water is doing, simply just how much water no matter really what it is doing. One cup of stale water or one cup of boiling water or one cup of spilled water etc. If we need it in a recipe we know how much that is.
If we talk about 1 coulomb then we are just talking about a set 'number' of electrons (which I could put down the number but its not needed to make this point err.. or to ask this question). So one coulomb is one coulomb, be it in a battery with other sets of one coulombs all waiting for their turn to flow through the circuit or if it be sitting in a capacitor etc... if we talk about “what” that 1 coulomb is “doing” then we add a different name to the coulomb.
So if we talk about one amp then we know it is a (single) coulomb traveling through the circuit with a set time and through a set amount of resistance...
OH GOD.. I really hope this comes out simple to everyone. heh.. oh well I have enjoyed the debate you all have done. great job everyone!
