Question
Explain how the discovery of the Voltaic cell was made?

Answer

Two Italian scientists, Alessandro Volta and Luigi Galvani, are known to have discovered the Voltaic cell, also called the Galvanic cell. Galvani noticed a dead frog’s leg kicking when touched with two different metals, copper and iron. He believed the electricity that came from the frog itself stimulated muscular motion. But Volta thought that the electricity came from the metals. He tested this using saltwater-soaked paper in place of a frog’s leg and got the electric current. The two scientists thus agreed that the combination of metals and liquid generated an electric current. Thus, the first battery was invented.
