Alternating current

He had been working under the current electrical powerhouse, Thomas Edison, but needed to break away from Edison’s DC (Direct Current) and lay out his own path without being limited by Edison’s ego and business stature .A pivotal moment in the history of electricity, and the electrical industry, came down to lighting the Chicago World’s

So we all know Thomas Edison, but we didn’t really know what he did for us. So you ask yourself who is Thomas Edison, well he was an inventor and he was well known for it. Was he the greatest inventor of all time? He made the phonograph. Also he made one of the greatest invention and it was the light bulb, but you ask , How did he invent light. What was his childhood like? what was his education like? what inventions did he make? Did he get married? Did he have kids?

Even though, Edison failed when General Electric offered a proposal to electrify a project in Chicago using Edison’s direct current for $554,000, but lost to their biggest competitor, George Westinghouse, who offered a contract to power the fair for only $399,000 using Tesla’s alternating current [3]. Also, another failure in 1893 for Edison, when Niagara Falls Power Company decided to build power station and was convinced by George Forbes to award the contract

wireless communication. The system consists of a single master and multiple slaves with wireless communication based on WSN and a raspberry pi system that can either operate on raspbian linux operating system. The parameters that can be tracked are current, voltage, temperature, and water level. The Android app is made to control industrial automation automatically using cloud. Manager manages this app with specific username and password. Manager can control this app automatically or manually. Keywords-

computer Engineering Department, Kettering University Flint, Michigan, 48504 yedi2874@kettering.edu hhizirog@kettering.edu Abstract— Over-current in a power system is a situation when a larger than rated electric current exists through a conductor, leading to excessive generation of heat, and the risk of fire or damage to equipment Possible causes for over-current include short circuits, excessive load, incorrect design, or a ground fault. This paper presents the design and implementation of a microcontroller-based

Innovator or inventor, although many may think these two terms are synonymous, the fact is they are not. Clear in his determination that he was not simply an inventor like his rival Thomas Edison, he considered himself an innovator; he was a man who discovered new concepts and revolutionized old ideas to bring about change. Despite a life full of skepticism from society, Tesla was headstrong and determined to prove to his peers, and even mentors, that he was capable. He relentlessly worked and proved

electrical engineer, mechanical engineer, and futurist. He had many creative ideas that had really change the world, but he had many more inventions that could had an impact towards society. There were some ideas he had created; for example, alternating current, harnessing and distributing light, and many more. His thoughts towards distributing and harnessing light was the lead creation of the Tesla Coil; in addition, an article, Nikola Tesla Inventions that Changed the World described how “Nikola

In my Serbian culture, there is a common saying “A smart man learns from the mistakes of others, a stupid man, from his own”. In this culture, sharing knowledge from mistakes to books to recipes is considered the norm and all of the social interactions and relationships are built on and around the act and idea of sharing knowledge. Under similar context, Bhartrihari once said “Knowledge grows when shared”. Personal and shared knowledge influence one another and develop intellect of the society. They

There are some famous inventors that I think have changed America’s history because of their inventions. Eli Whitney inventing the cotton gin, Nikola Tesla inventing the first AC motor, and Elijah McCoy inventing the lubricator for steam engines. Nikola Tesla was originally from Croatia but then moved to the United States in 1884. He there created the first ever Air Conditioner motor in New York also where he met Thomas Edison his future rival. One day Nikola Tesla was walking somewhere with sand

electronics both in AC and DC current source and compare the movement of electronics in those conditions. For better understanding of the electromagnetic induction in transformers, we observe the brightness of the bulb by changing the number of the loops in the coil, varying the magnitudes of the input ac current and also varying frequency. INTRODUCTION Faraday 's law: A time-varying current produces a magnetic field, and a time-varying magnetic field produce an electric current. The magnetic field
