1.	The emf method of the voltage regulation is applicable only to cylindrical rotor alternator due to ___________(a) resultant air gap flux is not affected by angular position of rotor(b) uniform angular position of rotor(c) non uniform angular position of rotor(d) saliency of the poles is a trouble while estimating the emfThe question was posed to me in semester exam.This interesting question is from Voltage Regulation of an Alternator in division Synchronous Generators of Electrical Machines
Answer» The correct answer is (a) resultant air gap FLUX is not AFFECTED by ANGULAR position of ROTOR Easy explanation: It is so because resultant air gap is unaffected by rotor position.
