Electrical Device Between Two Circuit Through...

INTRODUCTION The transformer is an electrical device which transfers energy between two circuit through electromagnetic induction. Transformer may be used as a safe and efficient voltage changer to change the Alternating Current voltage at it’s input to a higher and lower voltage at its output without changing it’s frequency. Other uses include current conversion, isolation with or without changing impedance and voltage conversion. A transformer consists of two windings of wire that are wound around a common core and it provides tight electromagnetic coupling between the windings and makes a couple. The core material is may be of a laminated iron core. The coil that receives the electrical input energy is referred to as primary winding, the output coil is secondary winding. An alternating current flows through the primary winding coil of a transformer generates electromagnetic field which varies in its surroundings and induces a varying magnetic flux in the core of a transformer. The electromagnetic field varies in the vicinity of the secondary winding induces an electromotive force in a secondary winding and appears as a voltage across the output terminals. If a load is connected across the secondary winding, a current flows through the secondary winding and drawing power from the primary winding and its power source. A transformer cannot operate with direct current(DC). When connected to a Direct Current source, a transformer typically produces a very short outputShow MoreRelatedApplications Of Faraday s Law Of Electromagnetic Induction1933 Words   |  8 PagesLaw of Electromagnetic Induction Prepared by: Ravi Ramlogan ID# 61928 Date Submitted – 01/10/16 Summary: This report looks into electromagnetic induction as an incredibly useful phenomenon with a wide variety of applications.

Government Productivity Essay - 975 Words

1.) Productivity is defined as the relationship between resources used and results achieved ¹. Improvement in this area means either obtaining more and better program output from a given level of resources or using fewer resources to maintain or improve a certain level of output. The federal government has a vital stake in improving the productivity of state and local governments for two primary reasons: (1) the national economy is strengthened as a result of improvements in the productivity and fiscal prospects of this key sector; and (2) the effectiveness and efficiency of the multitude of federal grant and regulatory programs using state and local governments to implement federal policies are directly related to the management capacity†¦show more content†¦According to Public Administration in America there are two useful ways to asses the productivity: (1) programs in which output is more easily measurable or quantifiable such as the unit-cost measurement of productiv ity (the upkeep of park facilities, pothole repair, etc.); and (2) concerns programs or functions in which output is harder to measure like provision of police, fire protection, or administration of federal unemployment of public assistance programs ³. There is the need to stress improving organizational and processing procedures. This can be done by the use of technology such as e-gov and management information systems. Also, computer and software applications can make a difference in large education systems, unemployment compensation, retraining, welfare-to-work, and monitoring capital construction programs. The importance to maintain and improve productivity of our government programs. It is very important that we improve productivity of government programs. In this economy we need to be able to cut costs wherever possible, this enables us to do so. It also would limit the amount of involvement and confusion it would bring if we dont improve them. The efficiency as we improve w ill also be developed. 2.) The new Department of Homeland Security combined 22 agencies and more than 200,000 employees.

Health Ethics for Criminalizing Domestic Abuse- myassignmenthelp.com

Question: Discuss about theHealth Ethics for Criminalizing Domestic Abuse. Answer: Changes in health law related to fraud and abuse: Several incidences of fraud and abuse are reported within health care context. Many health law and regulations have been framed to take appropriate action against perpetrators of abuse and control future care of fraud and abuse. The most recent law related to addressing and criminalizing domestic abuse was implemented in Saudi Arabia in 2013 and it gave the governing agencies the authority to investigate about abuse allegations and take steps to maintain the safety of abuse victims. Currently, victims are protected from many cases of fraud and abuse. However, in the past, such stringent laws were not framed to protect people from abuse. Currently, legislation gives power to Gulf countries to act against abuse cases. However, still corruption laws are not uniformly enforced and punishments are selective (Vlieger, 2012). Effectiveness of the efforts to control fraud and abuse Two strategies implemented in Saudi Arabia to address abuse and fraud includes the campaign related to domestic violence and the single contract policy for fraudulent practices. The Saudi cabinet in 2013 approved law to make domestic violence a criminal abuse. However it has not yet been criminalized in the country. One major effort that acted against the domestic violence case included the No More Abuse campaign, which promoted existing legislations to criminalized domestic abuse. The campaign was highly successful as it changed Saudi mindset regarding complaining for abusive behaviour and encouraged people to talk about it (hrw.org, 2018).Fraud and abuse in health insurance is also a major issue in health care and the implementation of single contract health insurance policy in Saudi Arabia has played a role in curbing fraudulent practices and manipulations in the health care sector. This effort has boosted the growth of health sector and ensured the expansion of health insurance t o employees (Woolhandler Himmelstein, 2017).

Art Research Essay Example For Students

Art Research Essay I cant believe it! I was just assigned the worst possible research paper topic ever by my history and language arts teacher! We have to be an art detective and discover the meaning of a piece of art. I had absolutely no interest in art so I knew writing this report would be nearly impossible. I began my search for a piece of art that was of some interest to me but I found absolutely nothing. Nothing was appealing or cool at all. I was beginning to see failure in my future. I still havent found what piece of art Im doing. I have searches through books, websites, and articles and still I had nothing. It was over. I was going to be stuck doing a piece of art I hated. But just as I thought that something miraculous happened. My eyes stumbled upon apiece of art that finally grabbed my attention. It was a sculpture. It was the Sphinx of Giza. This monument caught my eye so fast I knew this was the piece I should do. It worked out perfectly. No one had chosen the Sphinx so things were already looking better. I am excited to have found something that has some interest to me. I began my research immediately so I could get this thing over with. My first set of plans was to take a plane to the land of the Sphinx and meet the beast faced to face. I board my plane and in a little less than a day I am in the presence of one of the worlds greatest monuments. After walking for a few miles I am here at the Sphinx. I examine the enormous sculpture. It appeared to be made out of limestone (Schiff 108). The pieces of stone are incredibly large. Building this piece must have been a task for many men. The stone was probably moved around by either dragging the pieces of limestone or putting something underneath the limestone so it could roll and be pushed with much ease. I get closer to the Sphinx to get a better look and I notice something between its paws. It was a stone tablet with hieroglyphics on it. I study the hieroglyphics for a good chunk of time and understood almost all of it. From what I could understand, the Sphinx was built by the Egyptians and commissioned by King Khafre in about 2500 BCE (Baines 52). Its soul purpose is to watch over the pyramids of Egypt and all the kings that had died (Baines 52). I step back to take another look at it. The combining of the pharaohs head and the body of a lion was fascinating (Brockman). The body of a lion symbolizes speed, strength, and quick thinking; while the kings head shows power, intelligence, and wealth. When these traits are combined, an incredible being is formed. This explains why the Egyptians decided on a kings head and a lions body to guard over the pyramids. This shows that the Egyptians felt very strong about the after life, so they selected an incredible being to keep watch over them. The statue must have been a very powerful figure in the times of the pharaoh. The monument is a whopping 240 feet long and 66 feet high (Krysteck). The monument made the pharaoh seem even more powerful, a person you would never want to mess with. The Sphinx conveys a very powerful message. It makes me feel belittled due to its size and meaning. It amazing how much a non-living being could affect so many lives in so many different ways without doing anything. It also made me feel I was subject to the pharaoh and I had to perform his every will, or I would face the wrath of the sphinx. .u73cc29076296e9b471ed0e5fd38d553f , .u73cc29076296e9b471ed0e5fd38d553f .postImageUrl , .u73cc29076296e9b471ed0e5fd38d553f .centered-text-area { min-height: 80px; position: relative; } .u73cc29076296e9b471ed0e5fd38d553f , .u73cc29076296e9b471ed0e5fd38d553f:hover , .u73cc29076296e9b471ed0e5fd38d553f:visited , .u73cc29076296e9b471ed0e5fd38d553f:active { border:0!important; } .u73cc29076296e9b471ed0e5fd38d553f .clearfix:after { content: ""; display: table; clear: both; } .u73cc29076296e9b471ed0e5fd38d553f { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u73cc29076296e9b471ed0e5fd38d553f:active , .u73cc29076296e9b471ed0e5fd38d553f:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u73cc29076296e9b471ed0e5fd38d553f .centered-text-area { width: 100%; position: relative ; } .u73cc29076296e9b471ed0e5fd38d553f .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u73cc29076296e9b471ed0e5fd38d553f .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u73cc29076296e9b471ed0e5fd38d553f .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u73cc29076296e9b471ed0e5fd38d553f:hover .ctaButton { background-color: #34495E!important; } .u73cc29076296e9b471ed0e5fd38d553f .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u73cc29076296e9b471ed0e5fd38d553f .u73cc29076296e9b471ed0e5fd38d553f-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u73cc29076296e9b471ed0e5fd38d553f:after { content: ""; display: block; clear: both; } READ: Menschenschreck If The International Financiers In And Outside Europe EssayIt is a very creepy feeling when I was around it. It makes a person feel like a slave and incredibly helpless while in the sphinxs presence. I looked at the sphinx one last time and walked away. I was disappointed to be leaving Egypt already. It was an experience I will ever forget. Ever since I got home, I just could not keep my mind off this incredible art piece. What I was most curious about was what influenced Khafre to have this done. The most probable possibly is that he wanted to protect himself and other pharaohs in the afterlife. Another possibility is he could have been trying to pay tribute to the gods and his ancestors. Or it could be simply that he wanted to show off, so he had this built. Another thing that kept me on my toes was the fact that the nose was almost completely gone. One theory is that during French occupation, the French found the nose and the used it as target practice (Wickersham). Im sure the Sphinx had plenty of fun with them in the afterlife. The last thing on my mind was the beard only being about fifteen percent of what it originally was. One reason is that it took damage during French occupation, and another reason is that the weather may have damaged it (Brockman). It is odd that the weather damaged the sculpture but preserved it at the same time (Beardless 36). It was finally time to turn in my art project. What started out as a very lame assignment ended up being pretty fun and interesting. When my teacher graded my project he was dumb founded. I did such a good job he gave me an A! It was the best grade I received from him all year on a major assignment. Not much could have gone better.
