This generator has a rotor that acts as an armature and a stator that provides an electromagnetic field due to its staticness. As the rotor rotates in the field it cuts through lines of force and produce the desired output voltage in the end. This output voltage can be varied because the induced voltage into the armature is highly dependent on the rate at which magnetic lines of force get cut by the metallic ring (Keljik 2013). These generators are used in applications involving minimal power.
2.2 Rotating Field Generator
Keljik (2013) discussion on the rotating field type generators reveal that voltage is induced into stationary conductors by the magnetic fields that move past them. This type of generator is so far the most widely used. One advantage of this set-up is that it enables the handling of large amount of current due to the absence of sliding contacts. Furthermore, the whole output circuit is insulated. The output power take from stationary windings enabled connection of output through fixed terminals.
2.3 Polyphase Generators
Let us consider a polyphase generator as a three-phase AC generator. The generator is thus designed to produce three-phase AC power through the building of more coils in the stator around the rotor. Zarudi (1998) reveals that there might be a connection between the windings of a polyphase generator of not. The most used polyphase systems according to Zarudi (1998) are those that are connected due to certain advantages. ...Download file to see next pagesRead More

...change their economic conditions. Certain theorists have even stated that individuals even remain poor as they give up and submit to the culture experienced by the poor class. Individuals who become a part of this culture feel that they cannot change their economic scenario. They give up on the idea of competing and they feel that they are inferior to others and do not have the power to change things around. Sociologists are basically conducting a stereotypical behavior when they suggest that an individual remains poor due to his own activities. This is because not everyone in the poor class gives up or are not future oriented, those who get the option and chance try their best to turn their current economic conditions....

Current Trends
...?Discuss current trends affecting social welfare. Do modern trends favor the solution of social issues? What are the most effective social welfare organizations today in your opinion, and why? Your response should be a minimum of 250 words and reference at least two scholarly sources (one may be the text) in proper APA format The United States is facing a massive budget deficit and a debt that is spiralling out of control. This is not good news for social welfare, which will probably find itself being cut back over the next few years. Very few elements of the United States budget are going to be immune from drastic cuts, so long as the Republicans maintain some control of Congress. The truth is that the longer term fiscal...

Current and Non-Current Assets as “Fixed assets” are the set of assets which can’t be easily converted into cash or not expected to become cash in a time span of one year. Another way of defining non-current assets is the assets that are not directly sold to the organization’s end customers. Fixed assets are generally classified in three line items: Long-term investments, property, plant and equipment and Goodwill and other intangible assets. Long-term investments are the investments made in bonds of duration more than 1 year or shares of other companies. The value of these investments may change over time which implies that the value that is mentioned in the balance sheet is thoroughly analyzed. The second line item is the set of...

Alternating Current and Direct Current
...the terminal has one hot and one neutral terminal. AC voltage is preferred by several people because a transformer is used to convert it into DC and it is very easy and a reliable source of getting direct current. A transformer consists of two inductors, the loops and turns present in these inductors are very different from each other. The number of turns usually determines the ratio of primary to secondary voltage. Electric generators have been made to produce alternating current, they can also produce DC but this can only be done by using a rectifier. A rectifier is made up of diodes which are also the most important part of a rectifier; the main use...

Current Technology
...?Wi-Fi Introduction A Wi-Fi is the type of internet network whose nodes are interconnected without any wires, and the remote transmission of information takes place by means of radio waves at the physical level (Wysocki 2005). Since all current high speed wireless networks are using IEEE standards, especially 802.11g, the term Wi-Fi is used to distinguish wireless networks from other traditional wired networks. This paper discusses how Wi-Fi works, what are its advantages and limitations, and what the future holds for this technology. 2. How it Works? Before getting started, it is important to have respective service packs installed in the PC. A service pack is “a service pack is a collection of updates and fixes” that...

Tesla and Alternating Current
...that Nikola Tesla became one of the few people whom Edison had not been able to steal an idea from and take the credit. Nikola Tesla arrived in the United States in 1884 as a great admirer of Thomas Edison and eventually found employment to redesign dynamos intended to generate direct current electricity for Edison's company. Very early on, however, Tesla became convinced that alternating current was superior to the means that Edison was spending his time trying to perfect. Edison's response was that Tesla was wasting his time and talent because he considered alternating current to be far too dangerous for public...

Current Issue
...The Measles Vaccination Debate With the airborne viruses increasingly becoming ommonplace in todays world, the risk of trasnferrable infections among children and adults have begun to hit an all-time high. The concentration of this high ratio seems to be concentrated in one area for children. Their risk of Measles infection has increased a thousandfold due to the misplaced fears of certain parents regarding the dangers of vaccinating against Measles. Their belief is that Measles can cause more health complications for their child later on while serving as a first line of defense against the primary virus. While the U.S. battles with the ranks of fearful parents, the the anti-vaccine movement has grown exponetially in Europe... Measles...
