When I was in the middle of the quagmire concerning my scooter batteries, someone mentioned that, in order to provide the best charge for his batteries, he installed a capacitor (I think that's what he said) on the positive side of the charging unit. Call me stupid; while I know about "Ohm's Law," as well as the basic elements with respect to how electricity works (i.e., electricity being nothing more than electrons traveling through a system that has some of the elements -- on the periodic table of elements -- that are able to 'transfer' electrons, as the outer shell has but one lone electron and therefore, electrons can travel through the process of transferring these electrons) -- I did take a few "double EE" courses while attending college -- but I never learned the "basics" of a circuit board, although I do realize that "electricity is, by nature, 'lazy,' as it will usually choose the easiest and shortest path -- I lack the knowledge of some of these other issues.
Therefore, my question, said in so many words, is: what does this device do? (capacitor) -- if that is what he used.
Thanks,
Mark
