I have several questions at once but I'd really, really appreciate your help. You see, I hope to do an experiment to investigate how to produce the highest possible voltage from a cell like Volta's Pile and I have the following metals at my disposal: Al, Fe, Mg, Pb, Zn, Cu. Instead of using felt as Volta did, I intend to use filter paper, yet before I start I'd like to know all the different variables that could affect my results. I'd just like some confirmation for some of the hypothesises I already have and I'm also wondering whether or not certain variables do actually affect the data. I know that one of the variables is the combinations of metals I chose, and I know that the highest voltage will come from a combination of a very reactive metal with a very unreactive metal but why? Also, if voltage = current*resistance, then shouldn't it be that the more layers in the pile, the higher the voltage? Lastly, do the concentration of the saltwater and the thickness of the filter- paper between the metals affect the voltage? If so, how? Thank-you very much in advance and I hope it's not too much of a hassle. - Francesca
