Hello again :)
I've got a serious problem. Generally I know why current flows (free electrons and voltage). But some days ago I was considering about regular battery and electrical circut.
Free electrons in wire flow along circut, ok, that's fine and understandable. But how does battery generates voltage? I know that there are some chemical reactions. But it's not the point. The problem for me is that potential is created by charges. Does it mean that electron in wire flows due to electrons condensed at battery? How do we get potential?
One more time - I don't ask you how we get current, but how do we produce potential? If we obtain it by electrons gathered at battery, do they flow too?
Sorry for my english, It's not my national language :)
