Supplies Notable Characteristics Alternating Current Generator Generator needs to create 35 kHz frequencies Noble Gas Gas should be low pressure Noble gas of Argon variety Glass Globe Clear glass that comes with one small opening or ability to make opening Ignition Coil Tesla coil wire or other

Electricity and Magnetism History Electromagnetism Originally electricity and magnetism were thought of as two separate forces. This view changed, however, with the publication of James Clerk Maxwell's 1873Treatise on Electricity and Magnetism in which the interactions of positive and negative charges were shown to be regulated by one force. There are four main effects resulting from these interactions, all of which have been clearly demonstrated by experiments: 1. Electric charges attract

Institute of Technology sankalpasawa@gmail.com Sam Al-Attiyah Department of Electrical Power Engineering KTH Royal Institute of Technology sam3@kth.se Abstract— The purpose of this paper is to analyse the impact of three different Flexible Alternating Current Transmission System (FACTS) devices on a power system and to analyse their capabilities with respect to various disturbances. FACTS devices discussed in this paper are Static Var Compensator (SVC), Thyristor Controlled Series Capacitor (TCSC)

Joshua Joseph Mrs. Burrow English 300 11/3/2017 Thomas Edison and Nikola Tesla: Their lives, inventions, and impact In the mid 1800’s two important people were born; those people were Thomas Edison and Nikola Tesla. The reason these people are important is because those two men would help shape a new age of advancements in technology with their work. Mankind would be changed forever with the work of these men. Electricity is an essential part for everyone in America and for most people around

• Teaching, learning and assessment are good and reflect students’ improving success rates. College strategies to improve retention and hence success rates are taking effect, and in-year retention is now high. Students’ progression to a higher level of study and to employment is good. • Teachers use their good subject knowledge and extensive industrial experience effectively to enhance students’ understanding and awareness. Teachers draw on their own experiences in the industry to illustrate key

Week 7 Homework Assignment Chapter 7 Circuit Analysis Techniques 15. Derive the Thevenin equivalent of the circuit shown in Figure 7.47a. Req= (R1+R2)//(R3+R4)= 5.2k//1.5k= 1164 x 10^3= 1.2kΩ Rth= Req+R5= 1.2kΩ+1kΩ= 2200 x 10^3= 2.2kΩ Vth= Vs= 9V 16. Derive the Thevenin equivalent of the circuit shown in Figure 7.47b. Req= R1+R2= 22+33= 55Ω Vth= Vs x R3/Req+R3+R4= 12V x 120Ω/55+120+51 = 6.37V Rth= (R1+R2)//(R3+R4)= (22+33)//(120Ω+51Ω)= 41.6Ω 17. Derive the Thevenin equivalent of the circuit shown

outbursts of creative genius that led to days of non-stop work, eventually resulting in his “register(ing) over 700 patents worldwide.” His most well known work revolved around the Alternating Current electrical theories. While this stood in direct opposition to the corporately backed efforts of Edison to promote a Direct Current network for electrical distribution, Tesla continued with the idea of transmitting electricity through the air, and free to all people. Edison scoffed at the idea, but even the

Electrifying Thomas Edison did not invent the lightbulb. He simply figured out how to sell it. Possibly the most underrated inventor created the alternating current and provided electricity to every person desired it. Without question, Nikola Tesla was a genius. He could memorize entire books and recite them at will, spoke eight languages fluently, visualized and built devices in his mind without ever writing anything down. Tesla was not just an inventor, his contributions were revolutionary. While

Ralph Waldo Emerson once said, “A hero is no braver than an ordinary man, but he is braver five minutes longer.” Yet, if you ask anyone else, he will likely give you a completely different definition of heroism. Heroism is an inconsistent social construct that all may interpret to suit their own wants and beliefs. My personal definition of a hero comes not from the virtues of man, but the flaws. While heroes today are often seen as perfect individuals with a single flaw in order to make them “relatable
