Dry cell
A dry cell is a galvanic electrochemical cell with a pasty electrolyte. A common dry cell is the zinc-carbon battery sometimes called the dry Leclanché cell, with a nominal voltage of 1.5 volts, the same nominal voltage as the alkaline battery. Multiple cells are commonly connected in series within a single case or battery compartment within a device to form a dry battery (or dry cell battery) of greater voltage than is provided by one cell.
A wet cell, on the other hand, is a cell with a liquid electrolyte.
Structure:zinc outer casting (anode)-layer of NH4 aqueous paste-mixture of powdered carbon & manganese IV oxide around a carbon rod (cathode)Mn is reduced from oxidation state of +4 to +3
A dry cell is realtively cheap and is the most common. It was the first commercial battery and therefore it had a big impact on society as it contributed to the development of things such as torches and portable radios.
