NEW QUESTION:
http://www.allaboutcircuits.com/vol_1/chpt_10/3.html
this page has the mesh law, I don't quite get why there is 2(I1+I2). I understand both I's, but given their explanation do not quite see why the 2 is there as the coefficient.
old question: I didn't want to start a new thread, I always feel like I am posting just for the sake of posting when I do that.

On this link, I have a question on one of last figures it has the parallel resisors and it shows the battery with both voltage source and Rinternal, (the one that they call the parallel-series combo. The say that all the voltage will be supplied right back to Rinternal leaving none leftover for R1, 2 and 3. I read over the explanation a couple times, and don't really get why there is none left over for 1,2 and 3, but there is all for internal. Logically I am thinking, shouldn't the voltage at very least have to pass over at least one of those resistors to get to Rinternal.
So I don't get why this is, if someone could explain this phenonema to me differently, or more simply, that would be greatly appreciated, thanks
