If a small voltage - say 1V, is applied to the negative terminal of a 1.5V alkaline battery (although I don't think the type of battery matters?) will this create a current between the 1V and the negative terminal until the charges are somehow balanced? If not, what will this situation do to the battery?I know you are able to connect batteries in series to achieve a larger voltage than a single battery, but I'm not exactly sure what occurs inside the batteries to make this occur. I've learnt quite a bit about electronics during my degree but the details of batteries haven't been explained at all and this problem above has always confused me. Thanks!
