Why can't I get my voltaic pile (penny battery) to work? Answered
I've been attempting to make a battery using the various instructables (https://www.instructables.com/id/Penny-and-Nickel-Battery/), but I can't get anything to register on the multimeter. I purchased sheet aluminum from the hardware store, and that doesn't work. I even purchased CuSO4, to see if that would help, but it still doesn't work! I follow the directions exactly, is there something else that I've been missing?
