This circuit has many drawbacks but it eliminates the need to build a circuit or run down to Radio Shack, although obviously for a science fair project one would presumably build a simple joule thief/recharger circuit. The design can be scaled up with additional cells wired in series or in parallel to increase … egbertfitzwilly (author) kclo421122 years agoReply. Its not a galvanic cell, there is only one metal ( Aluminum ) which reacts with a saline solution. There is an excellent explanation …

Electrochemical cells are classically prepared with a pair of electrodes made of different metals to establish a potential difference and drive a current, such as in Alessandro Volta’s original copper/zinc battery built in 1800. But David Avnir and Ofer Sinai … simple electrochemical cell. The researchers inserted the fabricated electrodes into a lemon, which served as the electrolyte solution, a tactic commonly used by schoolchildren to build circuits for science fair projects.

This is listed as a 5th grade science project, but if demonstrated along with the “Turning on a Light Bulb” experiment, it can be used in electricity experiments, or elementary science projects from about the first grade on. … Coin Battery Project Setup. Turn the voltmeter on to a DC Voltage setting that shows at least one, and if possible, two or more decimal points as shown in the photo. Test each coin battery cell to make sure it is working as a small battery by putting one lead on the …
