Advantages and Disadvantages of Ad and Dc Essay - 1295 Words

1 HSC PHYSICS MOTORS AND GENERATORS| AC DC Gather secondary information to discuss the advantages and disadvantages of AC and DC generators and relate these to their use. AC generators Advantages ïÆ' ¼ The slip rings of an AC generator have a continuous surface that allows the brushes to remain in contact with the ring’s surface. Thus the brushes in an AC generator do not wear out as fast as in a DC generator as they do not create an electric short circuit every half-turn. ïÆ' ¼ Therefore they required less maintenance and is more reliable that DC generators. ïÆ' ¼ AC’s voltage can be changed by transformers. It is more readily transformed to different voltages than DC. ïÆ' ¼ Because of this property, AC can travel longer distances on†¦show more content†¦By 1882, his company was installing DC generators and electric lighting systems. Edison’s company had created many electrical appliances that run on DC such as light bulbs and other home appliances. He had a vested interest in DC as he owned hundreds of DC power stations and all his companys electrical inventions ran on DC. DC DC a a American engineer George Westinghouse bought the USA patent rights for the AC transformer. Tesla’s invention of the induction motor in 1888 largely popularised the commercialisation of AC. o AC induction motors is run by continuously moving a strong magnet back and forth near copper/aluminium that induces eddy currents in the copper/aluminium plate, which will cause it to follow the movement of the magnet – generating rotational kinetic energy. o Because AC induction motors do not require a commutator (as kinetic energy is created by induction), it has the advantage of higher efficiency and lower maintenance as no contact of material is needed. o 90% of motors are AC induction motors – used in fans, hair dryers, fridges, washing machines and vacuum cleaners AC AC â€Å" Problems with DC ïÆ' » Power could only be transmitted short distances from the generator because of ïÆ' » split ring commutator wore out quickly, higher maintenance reduces efficiency and increased costs ïÆ' » there was no efficient method of changing the DC voltage so electricity produced at theShow MoreRelatedNetwork Service 3 Written Exercise Essay1303 Words   |  6 PagesïÆ'Ëœ What are the advantage of Redundancy? ïÆ' ¼ Advantages ïÆ' ¼ Disadvantages †¢ High cost to create redundancy network †¢ Increased broadcast storm in network ïÆ'Ëœ What is Remote Access? ïÆ'Ëœ Remote access is the ability to get access to a computer or a network from a remote distance.

Race, Ethnicity, Prejudice Free Essays

Race, Ethnicity, and Prejudice-Online Project At one point in time the U. S. Census defined someone as a â€Å"negro† if they were one-sixteenth black. We will write a custom essay sample on Race, Ethnicity, Prejudice or any similar topic only for you Order Now That is, if one of your sixteen great-great grandparents was of African descent (and the other fifteen were of â€Å"white† European descent), you were defined as â€Å"negro†. In Jamaica, people believed to be of â€Å"pure† African descent are described as black. People who are bi-racial are usually described as â€Å"colored†. In Brazil, there are even more differentiations of those believed to be of African descent. The point of all this is that our definitions are culture-bound and socially constructed. They are, therefore, not particularly scientific and change over time. This does not mean that race and ethnicity have no real meaning. They have meaning because we give them meaning. 1. What method do census enumerators use to classify people according to race? A census enumerator is a person who collects census data. Before 1960, census enumerators were themselves responsible for classifying people according to race. However, in 1960 there was a switch to self-reporting. From this point on, individuals were in control of classifying themselves. It was no longer the census enumerators who classified individuals, but individuals who classified themselves. Census enumerators would just compile the results. 2. Which categories of ethnicity are used by the census bureau? The categories of ethnicity and race used by the census bureau have undergone numerous changes over the years. At first, from 1790 to 1880, the census recorded only â€Å"color. † During this time period it was a person’s skin color that was of importance and there were three categories: White, Black, and Mulatto. The categories expanded in 1890 and consisted of five gradations: Black, Mulatto, Quadroon, Octoroon, and White. It was in 1900 that the word â€Å"race† actually appeared in the census. The question now asked for each person’s â€Å"color or race. † At this time the census used only two categories: White and Black. It wasn’t until 1950 that the word â€Å"color† was completely dropped and the census only asked for the person’s race. In 1960 people were able to classify themselves. Shortly following the census added the category â€Å"other. In 1977 there were four racial categories established: American Indian or Alaskan Native, Asian or Pacific Islander, Black, and White. Plus there was the â€Å"Other† category. Also, the census added two ethnicity categories: Hispanic origin and Not of Hispanic origin. 3. How have categories changed for the 2000 Census? Since 1977, the racial and ethnic makeup of the country changed significantly. There were no questions as to whether the previous standards still reflected the diversity that was present in the United States. So, with that, the categories for the 2000 census were revised. The categories now consisted of: American Indian or Alaska Native; Asian; Black or African American; Native Hawaiian or Other Pacific Islander; and White. The category of â€Å"Some Other Race† is also included. In regards to ethnicity, there are two categories: Hispanic or Latino, and Not Hispanic or Latino. Aside from changes in the categories, another significant change for the 2000 census is that respondents are allowed to check off multiple â€Å"race† boxes. 4. What problems do you see with the Census definitions? The diversity in our society is increasing. Putting people in categories is becoming more problematic because the categories are arbitrary; none of the groups have clear or unambiguous boundaries. Classifying people into a certain category is restrictive and doesn’t take into account that â€Å"people classified as â€Å"Asian and Pacific Islander† represent scores of different national and linguistic backgrounds, and â€Å"American Indian or Alaska Native† includes people from hundreds of different tribal groups† (Healey 13). The census definitions are very limiting and they don’t do diversity justice. Also, there is still no place for a number of groups among the categories listed. For example, where should we place Arab Americans and recent immigrants from Africa? † (Healey 13). I understand that it is unrealistic to have a category for every single group, but we should realize that the definitions used by the census, the classification schemes, have limited utility and application. In addition, there is a growing number of mixed-race individuals for whom there are no categories. Although currently that number is relatively small, it is projected to increase rapidly due to a growing number of marriages across group lines. How should those individuals be classified?
