Q:Why syn. generators r used for the production of electricity?
A:synchronous machines have capability to work on different power factor(or say
different imaginary power varying the field emf. Hence syn. generators r used for the production of electricity.
Q:What is the difference between synchronous generator & asynchronous generator?
A:In simple, synchronous generator supply's both active and reactive power but asynchronous generator(induction generator) supply's only active power and observe reactive power for magnetizing.This type of generators are used in windmills.
Q:1 ton is equal to how many watts?
A:1 ton = 12000 BTU/hr and to convert BTU/hr to horsepower,
12,000 * 0.0003929 = 4.715 hp therefore 1 ton = 4.715*.746 = 3.5 KW.
Q:why syn. generators r used for the production of electricity?
A:synchronous machines have capability to work on differentpower factor(or say
different imaginary pow varying the field emf. Hence syn. generators r used for the production of electricity.
Q:Enlist types of dc generator?
A:D.C.Generators are classified into two types 1)separatly exicted d.c.generator 2)self exicted d.c.generator, which is further classified into;1)series 2)shunt and
3)compound(which is further classified into cumulative and differential).
