In a dry cell the zinc cylinder serves as the
WebIn cylindrical Leclanché cells, zinc serves as anode and cell container. The cathode mixture (manganese dioxide and acetylene black) forms a bobbin with a centrally located carbon rod as current collector. WebA common dry cell is the zinc-carbon cell, sometimes called the dry Leclanché cell, with a nominal voltage of 1.5 volts, the same as the alkaline cell (since both use the same zinc–manganese dioxide combination). A standard dry cell comprises a zinc anode, usually in the form of a cylindrical pot, with a carbon cathode in the form of a central rod.
