Q. Draw a neat and labeled diagram of a dry cell.
A dry cell is a kind of battery that is used to run portable electrical devices such as remotes, torches, and many other items. They are only usable for a certain period of time and when it’s elapsed it is being replaced by another cell to keep the items running and working.
Explanation of the labeling of Dry Cell.
The cell is topped with a metal cap which protects the cell. Next, the cell includes a zinc container which is an anode whose base is a negative anode. The dry cell is lined with Porous paper which is a kind of insulating paper, it is a form of Cathode with a carbon rod. The area in between the cathode and anode is included with a mixture of MnO2 and a thick paste (NH4Cl )which is ammonium Chloride, ZnCl2 (zinc chloride), and charcoal. The porous paper lining helps the dry cell from having a direct connection between the anode or the zinc container and the paste which is a mixture of various chemical elements and becomes a bridge element in order to prevent the cell from any kind of damage.
