Lemon Battery Experiment
If you don''t the battery will not work properly. Connect a multimeter to test the voltage. Will the volts be higher if you make the chain longer and add more lemons? How Does the Lemon Battery Work? A battery generates electricity by passing electrons between two. different metals (one that is positively charged and one that is negatively ...
Saltwater Pentacell
The five cells make up a battery when they''re connected in series. (A battery is two or more electric cells that are joined together.) The five-cell battery has five times the voltage of each individual cell. It takes a minimum voltage to light an LED. If you don''t have enough cells, you won''t provide the necessary voltage.

A project of University of California, Berkeley''s Lawrence Hall of Science. Major funding was provided by the National Science Foundation (Award #0735007), Institute of Museum and Library Services (Award #CAGML-246996-OMLS-20), The Camille & Henry Dreyfus Foundation, and Oracle.
Experiment 2: Faraday Ice Pail
touching our hand to it, they will run off through our hand. If we then remove our hand from the pail and then remove the positively charged metal ball from inside the pail, the pail will be left with a net negative charge. This is called charging by induction. In contrast, if we touch the positively charged ball to the uncharged pail ...
