Thesolution used is composed of caustic potash, two parts, to watersix parts, covered with a layer of paraffin oil. Both solution andcopper oxide plates require periodical renewal. Batteries may be coupled up either for pressure (voltage) orfor quantity (amperage). In the former case the negative (-)pole of the first cell is connected to the positive ( + ) of thesecond, and so on; and the current is obtained from the firstpositive and the last negative. The cells are then said to be inseries, and will give a current in volts equal to tha
