Replica of Alessandro Volta's apparatus consisting of series-connected galvanic cells to make up a source of electricity.
Zinc and copper plates stacked in alternation on top of each other are separated in each case by a piece of felt soaked in an electrolyte (salt water or acid). The electrolyte makes it possible for electricity to pass between the layers, allowing a voltage to be measured between the plates at the ends.
Connectors: two 4-mm safety sockets
Electrode diameter: 40 mm
Case dimensions: 135x85x40 mm3
