The discovery and further development of galvanic elements, better known as batteries, is of great importance for humankind. It has enables mobile power supply of various electrical devices, which is a big part of our today's living standard. The functionality of a battery is based on a unifying principle - the difference in electrical standard potentials of metals and elements. The electrical current, produced by a battery, can be determined with the help of the standard potentials of the used metals.
Students produce a galvanic cell by inserting a copper and zinc electrode into a potato. They measure the electrical current generated by the galvanic cell (potato battery) with a measuring instrument.
