How Does a 2 Cell Battery Operate?
A 2 cell battery operates by converting chemical energy into electrical energy. Each cell consists of two electrodes: the anode (negative terminal) and the cathode (positive terminal), separated by an electrolyte. When the battery is connected to a circuit, a chemical reaction occurs at the anode. This reaction releases electrons, creating a flow of electric current.
The current travels from the anode, through the circuit, and reaches the cathode. As the electrons move, they provide energy to power devices. Meanwhile, the electrolyte facilitates ion movement between the electrodes, allowing the chemical reaction to continue.
Both cells work together in series, effectively doubling the voltage output compared to a single cell. This configuration enables devices to receive a higher voltage, which is essential for efficient operation. Thus, a 2 cell battery functions through chemical reactions and electron flow, providing a reliable source of power.
