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 is electricity. Following the publication of Ohm’s law, Faraday would publish his findings on induction in the 1830’s. That same decade the DC generator, and transformer were invented, and followed in the 1840’s by the invention of AC generator. Communications technologies advanced at an incredible pace. Sömmering would design the first multi-line telegraph, and Morse would perfect this into a practical single wire design. The work of Charles Wheatstone in telegraphy and Heinrich Hertz in wave theory, paved the way for modern communications. Alexander Graham Bell invented the telephone in 1876. Èdouard Branly would make the contribution of a detector that allowed for the invention of the radio. Guglielmo Marconi and Alexander Stepanovich Popov would develop the first radios. From the invention of the battery to the first intercontinental telegram transmission, the advances in electrical technologies in the 19th century made possible the technological boom of the 20th and 21st centuries in comm...

As the late 19th century progressed, technological ideas and inventions began to thrive. The notion that technology would impact life as we know it was an unbelievable idea to comprehend. People had no idea that something so simple such as the light bulb would become so vital to them and for century’s to come. Inventions such as, the typewriter, barbed wire, telephone, Kodak camera, and electric stove were created, however the major inventions created and use tremendously today are, Medicine, Electricity, and Transportation.

Scientists of the time only comprehended the concept of generating electricity through the uses of “electromagnetic spinning machines,” but it was only until Benjamin Franklin conducted his infamous kite experiment that scientists found lightning is of the “same essence” (Burdon)(Brown). In the novel, Frankenstein “called upon the lighting” to start the monster’s heart, but the how did he attract the lighting to that very place (Taranovich)? As introduced earlier, Volta studied retaining electrical charges and attraction. This idea of calling about electricity from nature is seen as an aspect “only God can control” (Taranovich). Inspired by Mary Shelley’s novel, Nikola Tesla found that using a placing a rod high in altitude connected to a conductive metal in the ground has a high chance of being struck by lightning leading the name of this contraption, the lighting rod. Tesla also incorporated this into a device that would harness the natural electrical energy just as Volta had studied. Tesla invented the tesla coil design to “carry current from power supply to load” (Brown). This process became known as electrical induction, or as capacitive coupling in more modern times. Through this, scientific developments such as particle accelerators, radio and telegraphy became possible
Every invention ever known to man had pioneers or people who contributed to the creation of the product. Radio had many pioneers that allowed for its creation and their names are Heinrich Hertz, Nikola Tesla, Ernst Alexander, Edwin Armstrong, Guglielmo Marconi, Lee DeForest, Frank Conrad, Reginald Fessenden, and Edward Armstrong. It all started with a German physicist named Heinrich Hertz who in 1884 proved that you could transmit and receive electric waves wirelessly. Hertz thought that the work he had done had no use whatsoever but little did he know that what he done is considered the fundamental building block of radio, and that is the reason why every frequency measurement is named after him (Short). In that same year a Serbian-American inventor named Nikola Tesla came to the U.S and sold patents to his inventions to a man named George Westinghouse. After that Tesla established his own lab which is where he built the tesla coil , an induction coil that is still used in radio today (Short). The next progression of radio focused on more than just the transmission of waves, the new focus was transmission of speech. The first to begin to add speech into the radio mix was Ernst Alexander, a Sweden born inventor who developed the first alternator to make speech transmission possible (Short). This was so new to the s...
As early as 1600 to present day 2012, electricity is being used for the most simplest objects to the most complicated gadget‘s. Today people take electricity for granted simply by just leaving a house light on. Whereas back in the 1600’s a candle was the main source of light. In 1600, a English scientist by the name of William Gilbert was the first person to use the term Electricity. He also wrote about the electrification of many substances. With William Gilbert’s success, many scientist have followed his foot steps which led to the great inventions that we have today. Scientists like Benjamin Franklin, Thomas Edison and Alexander Graham Bell have proved and invented many creations that without, humanity would be lost. Benjamin Franklin proved that electricity and lightning are the same and from this he made the lightning rod, which protects buildings and bridges from lighting damage. Alexander Graham Bell invented the telephone and without this invention communication would lack in today’s society. Thomas Edison was the most productive electrical explorer. He invented the light bulb in 1879 and many other products electricians use or install today. With Edison’s invention, about 499 billion kilowatts-hour are used today for lighting in residential and commercial areas. Electricity is used everywhere throughout our house and every part of our life and without electricity we would still be living in the 1600’s. The discovery of electricity has effected the human experience immeasurably, without the discovery of electricity humans would be deprived of telephones, cars and computers which would cause our lives to be completely different.

Despite the short amount of time since the introduction of the smartphone, the rapid development of the software and technology has had a tremendous effect on the everyday life of society today. The concept of communicating through a telephone was developed in the 1870s. Devices to transmit speech electrically were designed by Elisha Gray and Alexander Graham Bell, but Bell's design was patented first. On March 10, 1876, Alexander Graham Bell achieved one of his greatest successes in the making of the telephone. This brought upon a major change in communication and gave leeway to the improvement of the telephone in the days to come (Bellis, 2013b).
The history of engineering goes back into the 19th century when Alexander Volta (1745-1827) made a remarkable discover regarding the nature of electricity (Cosgrove 749). He discovered that electrical current could be controlled and could flow from one point to another. By the time the mid-19th century came about the rules for electricity were being established. During this time electromagnetic induction was discovered by Michael Faraday who lived from 1791 to 1867 (749). Also during this time Samuel Morris invented the telegraph in 1837 which relies on the principles of electromagnetic induction (749). Alexander Graham Bell, who lived from 1847 to 1922, created the telephone which also uses electricity in order to operate (749). Through the success of the telephone, Bell Telephone Company was established. In 1878, the light bulb was finally invented by Thomas Edison who lived from 1847 to 1931 (749). Off the principles of Faraday’s electric motor from 1821, Nicholas Tesla invented a more efficient and powerful electric motor in 1888 (749). To make these inventions be more significant, effort was expended to make better motors and transformers and to enhance the power needed to make them function. Through these inventions during the middle 19th century, it led to the capability of lighting homes and cities through the use of electricity, and it also led to the creation of the telephone communication system (750).
The Effect of Electronics on Communication Electronics has played a major part in communication and the developments of it. The first ways of communication not by just talking were the uses of cans and a piece of string. This worked by the vibrations of the voice vibrating down the string and into the other person’s can. The next major development was the invention of telephones. The first telephones were large and ugly with large numbers and were difficult to hear, and the switchboards were done manually by women and children.
First of all the developer of this innovation was Nikola Tesla ; a Serbian- American Engineer and Physicist. His first project was the AC motor generator and the development of transmissional technology. His success with this lasted until he had an argument with his boss because of his mad scientist
