Electrical telegraph

news and messages were transmitted was the Pony Express. There were some electrical communications, but they were either too slow or too complicated. Railroads were helping expand the country quickly, they were connecting cities to each other, but there needed to be some form of communication to pass messages throughout America. That is what Samuel Morse and his new system of telegraphy successfully achieved. In the early 1800’s, all of the required parts that were needed to build an electrical communication system had been discovered. The most important of these were the battery by Volta, the relationship between electric current and magnetism by Oersted, and the electromagnet by Henry (Oersted). The only thing that…

The telegraph was a very simple and efficient method to send messages developed by Samuel Morse and a group of other inventors in the 1830s and 1840s. A combination of dots and dashes were assigned to each letter. To send a message the operator key would be pushed down to complete the battery’s electrical circuit and the amount of time you held the operator key would determine if it is a dot or dash. This would then transmit an electrical signal through the wires laid in between stations to the…

One day a long time ago the world was changed. It was changed by the name of Samuel Morse. Samuel Morse had invented the telegraph. A piece of equipment that not only would change the world but it would help win wars and help people communicate with loved ones. Samuel Morse had paved the road for future inventors like the inventor of the telephone Alexander Graham Bell. Samuel Morse should have credit for helping invent the phone. He changed the world. Before the telegraph was invented…

Telegrams Always Bring Bad News “It’s only for a little while,” my father explained the day he left. “I’ll be back before your birthday.” But my father left our home in Cleveland, Ohio for New York City months ago. Today is July 6, 1892… four days from my birthday. I’ve heard my mother and father discussing tragic railroad accidents many times, so when my father revealed that he was taking a train to New York, I was shocked. “What about all the horrible things that could happen?” I asked my…

contributions to the design of alternating current electricity. Though Edison is more well known, both men contributed greatly to the field of electrical science and should forever be remembered. Thomas Edison was born on February 11th, 1847. He grew up in Milan, Ohio, and later moved to Michigan. As a child, he was highly intelligent and showed…

Once he returned home he began drawing the plans for his electrical telegraph. His first model was composed of a wooden frame, which would hold an electromagnet, paper, and a marking pencil suspended from a pendulum. The pencil would mark on the paper as the electric circuit was opened and closed. What is now known today as Morse code is what Samuel Morse created when he used dots and dashes in his telegraph. To continue his experiments and research he needed financial support. Fortunately,…

used the train cart to set up a small laboratory, allowing him to conduct his chemical experiments there. Thomas’s traveling job, as a telegraph operator, that he pursued at age sixteen allowed him to play around with chemistry, soon realizing all that it had to offer. Despite what most people believe, Edison did not always create his inventions from scratch. In fact, a great amount of his working hours were devoted to disassembling and reassembling other people’s work. Edison began…

AT&T has its roots in the invention of the device that would change the communications history of modern man. In 1876 the Bell Telephone and New England Telephone and Telegraph Companies were created. They became known as the Bell System and were a monopoly for telecommunications in the United States. In 1885 the American Telephone and Telegraph Company was formed as a subsidiary of the Bell System to build and operate a long distance network. Its name was changed to AT&T Corp. in 1994. By 1913…

direction many times a second at regular intervals, typically used in power supplies. The alternating current was important to humankind because a direct current is only for low voltage uses not powering a whole house. The alternating current is used in our everyday life, in our houses,schools, computers, and other stuff. This is done by the use of a transformer that a electric company comes and installs on every street that is needed, then they send a flow of high voltage power, which is then…

generation, transmission and distribution? Task 4 (D1) Electricity has greatly evolved from what it once was, to be fit for our modern day consumption and usage. Electrical engineering was first pioneered in the early 19th century, and great progress had been made by the time the 19th century came to a close. Most of the advancements were made by the likes of Thomas Edison, Nikola Tesla and George Westinghouse; who all aided in making electricity what it is today. In 1878 Thomas Edison started…
