A synchronous machine is one of the important type of electric machines. Large a.c networks operating at constant frequency of 50Hz rely almost exclusively on synchronous generators, also called the alternators, for the supply of electrical energy. Private, stand-by and peak load plants with diesel or gas-turbine prime movers also have synchronous generators. Synchronous motors provide constant speed industrial drives with the possibility of power factor correction. Synchronous machine are generally constructed in larger sizes. Small size alternators are not economical. The modern trend is to build alternators of very large size capable of generating 500MVA or even more. The synchronous motor is rarely built in small sizes owing to superior performance characteristics and economical construction of induction motors. 1.2 OPERATING PRINCIPLE The operating principle of a synchronous machine is fundamentally the same as that of a d.c machine, but, unlike...

...Introduction This essay intends to explicitly compare Karl Marx and Emile David Durkheim ideas on religion from a sociological and functionalist perspective. Functionalists’ belief that religion is beneficial for both the community and its members e.g. it unifies the society which in turn gives each individual member a source of support when they need it. It will begin with their brief historical backgrounds, definition of religion as well as their similarities and differences in studying it. Karl Marx Marx was born in Prussia on May 5, 1818. He began exploring sociopolitical theories at university among the Young Hegelians. He became a journalist, and his socialist writings would get him expelled from Germany and France. In 1848, he published The Communist Manifesto with Friedrich Engels and was exiled to London, where he wrote the first volume of Das Kapital and lived the remainder of his life (Engels, 1869). Marx is considered as one of the founders of economic history and sociology. Emile Durkheim According to Jones (1986) “David Emile Durkheim was born in France, on April 15, 1857 and raised in a Jewish family with his father as a rabbi. Emile was, thus destined for the rabbinate, and a part of his early education was spent in a rabbinical school” (p.12). Durkheim is considered the father of modern sociology and well known for his work on Division of Labour in 1912. Definition of Religion Both Marx and Durkheim have rather contrasting definitions of what religion...
