I'm 15 and recently started electronics and I just had a question about batteries.
(I've been told by people on physics stack exchange to come here to have my question answered).
From what I understand and according to the videos I've watched, a battery creates a potential difference (votlage) by accumulating more high concentration the negative plate than the positive plate. Therefore the higher concentration of electrons, the higher potential difference (voltage).
Could someone tell me if this is correct?
