Lemon Battery with Voltmeter
The Lemon Battery, is a Galvanic Cell, also known as a Voltaic Cell.
It is an electrochemical cell in which 2 electrodes (Zinc and Copper) are separated by an electrolyte (lemon juice- acidic in nature). This cell derives electrical energy from chemical reactions taking place in the cell.
This simple cell is named after Luigi Galvani & Alessandro Volta, both of whom contributed to inventing and developing the electrochemical cell in (~1780s-1790s). Luigi actually used frogs as the electrolyte.
Why is our Lemon Battery different? We include a Voltmeter so you can conduct meaningful Scientific Experiments to compare voltages of different Galvanic Cells! Of course you can light an LED (also included)!
Kit requires a 9V battery, not included in the kit.
Kit contains small parts, not suitable of children under 3 years.
Note: Over time, Zinc will oxidize and will lose its capability to produce a voltage; simply replace the nails (& Lemons)! Head over to our Spares collection to order Zinc & Copper Nails. Spare Voltmeter for other DIY projects also available.
