Thanks kscmac. I've a friend who suggests building a controller so that the current remains constant as the solution becomes more conductive. Is that what you mean by a current limiting diode, (he's the electronics wiz, not me).
I can purchase either .9999 silver wire, .9999 Canadian Maple Leafs, or both. What would be the current needed for either?
Does the amount of liquid or distance between anodes matter. I've read responses that disagree with each other. Thanks again.
