Major Discoveries in Electrical Communication in the 1800’s

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 Andrà © Marie Amperà ¨ 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 fr ogs 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 th e 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 thatShow MoreRelatedThe Development of Wireless Communication Leading to the Alexanderson Alternator Not much has1200 Words   |  5 PagesThe Development of Wireless Communication Leading to the Alexanderson Alternator Not much has changed in human nature in the past couple centuries. When we want something, we desire exactly what we want without deviation and we wish to have it quickly. This is as evident in modern times as it was in the late nineteenth and early twentieth centuries.

One of the fundamental bases behind these engineering feats is the harnessing of energy sources, such as electrical and heat energy. This has allowed for many innovations, for example power stations, transportation, communications and computers, which have all become critical to society and the modern world in which we live. 1 – Introduction It is almost impossible, today, to look around you and not seeRead MoreThe Invention Of Inventors : Inventing Solutions Essay1338 Words   |  6 Pagesand are even taken for granted. However, if we look back in time, we can see just how impactful these inventions were. This essay will discuss the many different inventions throughout history that changed the world we live in today, for better. One major invention that is underestimated today is clothing. The common cloth used today started out as cotton. Cotton strands are separated from the seeds of a cotton plant and those fibres are used to make fabrics and clothing.

The United States had a small, weak, economy, until the mid-1800s when inventions and innovations united and strengthened the economy. From the beginning of time, people have invented things and innovated to help expand their economy. Gunpowder, the printing press, language, the wheel, pottery, post offices, and man-made bridges are all examples of inventions that led to economic growth.

This new network provided faster connections between people, places, markets, armies, and government. Telegraphs carried very important time sensitive news. For the first time man could communicate with another man from a great distance changing everything from how we saw communication. The rises of new technological networks were filling America during the mid 1800s to mid 1900 s.
