Alternating current

Nikola Tesla (Nicholas Tesla) was not only an inventor; he was an engineer, physicist, visionary, and most known for, brilliant. Tesla was born July 10th 1856, in Smilijan, Austrian Empire, which is now modern day Croatia and moved to the United States in 1884 to continue his career in engineering. Tesla’s parents were both Serbian, his father was an Orthodox priest, writer and poet, while his mother was a creative and had the talent to construct things, especially her electronic every day household

AC MOTORS Task 1. Watch the video about AC motors and identify the main information. Take notesand then discuss the main points in pairs. Notes: Stator and rotor are means fixed part Robust Cheap Alternate is means change in current There are two type of motors: AC and DC motor. Task 2. Look at the illustration. In your own words, explain how an AC motor works. Use the words below. Define them using the term-class-differentiating characteristics method. magnetism

kind of electrical currents. It would be Edison’s direct currents against Tesla’s alternating ones. This disagreement would go on to shape the course of electricity across the country. It would later be known as the War of Currents. The War of Currents had a great impact

the United States and the World. Through hard work and many sleepless nights, Tesla was able to create a cheaper yet efficient electricity supply system, which relied on Alternating Current (AC), that would become the main supply system in America over rival Thomas Edison’s then popular supply system, which relied on Direct Current energy (DC), in the 1890’s. Some of his inventions and ideas, such as the Tesla Coil, and the idea of wireless communication, gave way to the invention of many other modern

influential historical figure from the gilded age because of how his innovations forever revolutionized our understandings of energy and technology. To begin with, Tesla’s innovation of alternating current or AC electricity was unique and crucial. Prior to Tesla, the world’s power was largely supplied using a DC or direct current system. Around

achieve an anticipated result (Unconventional Tactics…). A perfect example is the time Edison publicly executed an elephant, named Topsy, in an aggressive effort to maintain success. In the early 1900’s, the standard for electricity known as direct current (DC), invented by Edison, reigned supreme. This invention consistently generated Edison a substantial amount of revenue for discovering it. The reason Edison went to the extremity of electrocuting an elephant was to both demonstrate a point, but more

Intro Thomas Edison and Nikolas Tesla were two disputing geniuses. They were both key players in the course of electricity use and inventions. Edison “Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.” —Thomas Edison Thomas Edison was a businessman and good at improving ideas. Thomas Edison was born February 11, 1847 in Milan, Ohio. Edison was the youngest child out of his seven siblings. His mother was a school teacher and had a great

list of the greatest inventors and scientist of the modern era. Thomas Edison gets all the glory for discovering the light bulb. It was his one-time assistant and life-long arch-nemesis, who made (Nikola Tesla) the breaking throughout in alternative current technology that allowed people to use electricity cheaply in their house. When he came to America Thomas Edison had offered him lots of money to work for him. But Thomas Edison had actually tricked him about the money at the time. Nikola Tesla was

there have been critical elements of technology that have revolutionized the way humans live life. Examples of this are the creations of the wheel, the printing press, the airplane, and of course electricity. Each of these technologies caused the human race to be thrown forward into new eras of innovation, and none of these eras would have been possible without the inventors that started them. Through modernization, curiosity, and persistence, inventors have continued to change the way humans live

Edison’s Portrayal A dreamer, an inventor, and above all, Thomas Edison was an ambitious and ruthless businessman who manifested the deep determination to take over the electricity market. Edison’s portrayal in Moran’s book “The Executioner’s Current” holds much more realistic and in depth aspects of his personality, than shown in the short excerpt, “They Transformed the World” pertaining to “America’s greatest change-makers.” On top of being an inventor, as shown in the excerpt, Moran’s portrayal
