- Potato Battery
Video recorded in 2007.
When two different types of conductors are pushed into a potato chemical reactions take place charging them up - we have a simple electrochemical cell. A potato, zinc screw and carbon rod produce about 1V. We experiment joining a few of these cells up in series and then in parallel circuits to increase the total voltages and currents. With these batteries we power various electrical devices.
