Nikola Tesla Have you ever walked into a room, turned on a light, and wondered, “Who gave us the ability to do this?” Nikola Tesla is the man’s name. He invented Alternating Current, or AC, which is the electrical system that we use to power our world today. In this paper, I will be describing a few of Nikola Tesla’s innovations and how they inspired and impacted our way of life. HISTORY Before I start on his inventions, I will give a bit of history on the man that lit our world. Tesla was born

after their inventions (“The Life and Legacy”). Tesla discovered and designed the alternating current system, dynamos (electric generators similar to batteries), the induction motor, and the Wardenclyffe Tower project (“The Life and Legacy”). He was instrumental to the discovery and development of radar technology, x-ray technology, and the rotating magnetic field (“The Life and Legacy”). Tesla’s alternating current system forms the basis of the American electrical grid of today, the basis of the

people do not understand is the fact that if the “Wizard” had his way, there would be a power plant every several miles, scattered about the land like sprinkles on a cupcake. At the time, direct current was the only choice, inhibiting as it was. Then, thanks to a man names Nikola Tesla, an alternating current motor was invented, allowing much more efficient electricity travel. This is just one example of the impact Telsa has had on the modern world. The forgotten father of science, Tesla, is responsible

company in Paris to improve their direct current facilities, Tesla ventured to New York City to meet the esteemed Thomas Edison. Tesla did not care for Edison’s direct current power, and left his company to begin his own business of invention (Tesla: Life and Legacy). Little did he know that the inventions he created would change the lives of millions across the world. Nikola Tesla changed society in astounding ways through incorporating alternating currents into his complex inventions of the Tesla

to bring his plan to life. He succeeded many times with electrical generating equipment like the numerous variations of the Tesla coil. Alternating current is probably the most important invention of his collection. Without it, there would be no wall outlets for the easy plug-in of everyday devices. The world's population would still be using Edison's direct current method of electricity. Nikola Tesla may have seemed like someone who was not that important to the lifestyle of the modern era, but without

Company. While at Graz Technical University, Tesla had seen a demonstration of a generator run as a direct-current (DC) motor. Direct current is electric current that flows in only one direction. During the demonstration, the brushes and the commutator of the motor sparked violently. The brushes are devices that conduct the current in a DC motor. The commutator continually reverses the current so that the motor continues to rotate in one direction. Tesla believed a motor without a commutator could

What is Current. First off, what is current. Current is expressed in a unit called Amps. Amps are a measurement of how many electrons pass per second. That is to say, a wire with 40 coulombs passing any point in a 2 seconds would be said to have 20 Amps of current (40 Coulombs (a unit of charge given as 6.24x1018 electrons) / time in seconds or in this case, 2 seconds. The Amp is also known as Coulombs per second) Another trick about current is that it is measured in the movement of the positive

Tesla and Thomas also had more inventions than Tesla, also because Edison did a lot of work with the light bulb. Although they both had a big part in controlling electricity one was for Alternating Current electricity and one for Direct Current. Nikola Tesla was against Direct Current and left with Alternating Current and Edison was for DC and so Nikola and Thomas were up against eatchother to see which one was a much better use. Thomas Edison Thomas Edison’s full name was Thomas Alva Edison; He lived

Without the use of physics in the medical field today, diagnosis of problems would be challenging, to say the least. The world of medical imaging in particular has benefited greatly from the use of physics. Ultrasound is sound waves that have a frequency above human audible. (Ultrasound Physics and Instrument 111). With a shorter wavelength than audible sound, these waves can be directed into a narrow beam that is used in imaging soft tissues. As with audible sound waves, ultrasound waves must

Fuel oil Systems; Marine Engines are mainly designed to run on Low cost fuel such as Diesel Oil or Heavy Fuel Oil which contains high dense particles, waste residue and other contaminants. These materials should not be pumped into the engine directly as they will damage the engine and decrease the efficiency. So first these materials are to be removed from the fuel oil and then the purified oil is supplied to the engine for better performance. So, this plays a very important role in the efficient
