WebAug 10, 2024 · A battery is an electrochemical cell or series of cells that produces an electric current. In principle, any galvanic cell could be used as a battery. An ideal battery would never run down, produce an unchanging voltage, and be capable of withstanding environmental extremes of heat and humidity. WebUse a ruler to make sure you space the electrodes the same distance apart and insert them to the same depth in each potato (for example, 2 cm apart and 3 cm deep. The exact distances you pick may depend on the size of your potatoes). Figure 4. Copper and zinc electrodes inserted into a potato.
