Explain how a galvanic cell is used to produce electrical . energy. Galvani's frog united chemistry, physics. THE UNION of physics and chemistry began with the twitching of a frog's leg. In the 1790s Luigi Galvani lay a dead frog on a table. Also on the table was a static electricity generator. An assistant accidentally touched the nerves of the frog with a scalpel and the muscles of the frog contracted . 10/6/2015. Definition of Resistance and Impedance.
