well not really, though more of them will be moving in the (roughly) same direction past a given point; that is, after all, what "Current" is. It's not that the electrons run faster from end to end, hence increasing the current; it's that higher voltage crowds them in more densely: for yet another very imperfect analogy, more get stuffed into the subway train, but the train doesn't go any faster, and so more get out at their destination, per unit of time (hours if you live in New York!) -- The Silver List is a moderated forum for discussing Colloidal Silver.
