How do dry cell and batteries work?

Dry cells, commonly used in batteries, convert chemical energy into electrical energy through electrochemical reactions. In a typical dry cell, an electrolyte interacts with two electrodes (anode and cathode) to produce a flow of electrons. When the cell is connected to a device, this electron flow generates electric current, powering the device. The reaction continues until the reactants are depleted, at which point the battery needs to be replaced or recharged.
