1.	Which one of the following is the base reason to place field on rotor in the alternator?(a) Small power in field circuit(b) Insulation of high voltage is made easy on stator than on rotor(c) Huge power in stator(d) Large current in the statorThis question was addressed to me in unit test.I want to ask this question from Synchronous Machine Stability topic in portion Synchronous Machine Stability of Electrical Machines
Answer» Correct answer is (b) Insulation of HIGH voltage is made easy on STATOR than on rotor To explain I would say: Providing insulation BECOMES easier as the stator will be stationary.
