Major Discoveries in Electrical Communication in the 1800’s

Best Essays

The nineteenth century was a very prolific era of discovery in electrical knowledge and technologies that laid the foundation for modern electrical communication. During this period of time the foundations of modern electrically based technologies were discovered. The nineteenth century began with a debate between Luigi Galvani, and Alessandro Volta regarding the source of electricity in Galvani’s famous frog experiment. These debates lead to the invention of the battery by Volta, and the invention of Volta’s. Volta’s discoveries would lead the way for Ohm’s law several years later. However, before that discovery was made Hans Christian Ørstead discovered electromagnetism, which was then used by André Marie Amperè to show that magnetism …show more content…

Galvani noticed that when a metal scalpel was brought close one of the nerves in the frog that the frog’s leg would move. Galvani stated that the electricity observed in the frogs was intrinsic the nerves of the frog. Galvani used multiple different metals combinations to demonstrate the electric phenomenon. He would further demonstrate that metals were seemingly unneeded. He did this by manipulating the nerves and muscles of the frogs in such way that caused the same twitch, as when a metal object was brought near. The publication of his research in 1791 would peak the interest of Alessandro Volta. Volta was convinced that Galvani’s animal electricity was not the result of the animal tissues, but the metals within those tissues. In an effort to prove this Volta invented the battery . Volta’s battery was built out of alternating zinc and copper disks with cloth (or a similar medium) soaked in salt water [10]. Volta stated the following regarding the nature of electricity with respect to Galvani’s animal electricity: "Herein lies the whole secret, the whole magic of Galvanism. It is simply an artificial electricity, which acts under the impulse of contacts between different conductors” [9]. At this point Volta’s theory of electricity by contact was fully accepted. Just after Volta’s greatest discovery and before that of Ohm, Hans Christian Ørstead discovered magnetism. Ørstead conducted a series of experiments that
