ok, So I am in an entry level physics class (electricity & magnetism) and I am having trouble grasping the idea of voltage/electric potential. Wikipedia describes it as "electric pressure" but that is still pretty foggy. My professor relies heavily on mathematical derivations and barely says a word about topics conceptually. The mathematics has never been the problem its just I am such a visual learner and must be able to "visualize" what is happening at the most basic level. Now I am we are doing DC circuits and I am totally lost, because I can't understand what is happening on the atomic level.
