|Alessandro Volta, man and scientist
7. The invention of thw battery
The debate went on without any clear result until the final months of the century. Using the difference in potential due to contact between two different metals, Volta realised a circuit in series, by introducing a third, moistened conductor. This method of connection was able to draw electricity from all of the single elements together. He thus invented the battery.
The importance of the invention and its applications, which came about in a few months, seemed to prove the Como scientist right. His fame has since conquered the world. But the idea of animal electricity did not prove useless. Voltas invention was to give rise to electrochemistry, electromagnetism and the modern applications of electricity. Galvanis research was soon to develop into electrophysiology and modern biology.
