WebA dry cell is a device that uses chemical reactions to create energy. When the cell’s two electrodes are connected by a closed channel, the electrons are forced to flow from one end to the other. In a closed circuit, current flows due to the flow of electrons. Electrons travel from one end to the other thanks to chemical interactions. Depending on the nature of the dry cell, it can be classified as a primary cell and the secondary cell.
