Dead Frogs Once Powered Batteries

In early science experiments, researchers connected rows of dead frogs to generate electricity. These biological batteries served as crude power sources during the dawn of electrical discovery.

Long before chemical batteries were common, scientists used animal tissues to study electric currents. By linking frog legs in a series, they could create a continuous flow of power for their equipment. This practice helped prove that electricity was a physical force rather than just a mysterious life spark. While it sounds macabre today, this method was essential for teaching the basic principles of bio-electrics.
