Batteries 2
The invention of batteries was considered a great discovery by affecting our lives. Has it affected our lives for good or for bad, since the discovery of batteries in around 1800? Before the time of invention a number of discoveries had previously been made. Floriano Caldani (1756) observed that frog legs could be made to contract when a near-by static machine was discharged. Luigi Galvani (1786) rediscovered this phenomenon and apparently unaware of similar work by Jan Swammerdam more than a century earlier (1678), noted that a contraction occurred without external electrical force, when two different metals were placed into the muscles of a dead frog. The physicist Alessandro Volta (1792) discovered the difference in potential of metals in contact with electrolyte and developed the concept of the electromotive series. By 1800 Volta had perfected and described the first operating battery or pile “which functions continuously, its charge being renewed after each discharge; it possesses in fine an inexhaustible charge.”Since this time a lot of changes have occurred within the technology of batteries throughout the world. Batteries have opened many doorways towards the future and better living. The improvement through the
