Load angle δ is the angle between ____________(a) stator MMF Fs and r

1.	Load angle δ is the angle between ____________(a) stator MMF Fs and resultant MMF FR(b) stator MMF Fs and rotor MMF Fr(c) rotor MMF Fr and resultant MMF FR(d) stator MMF Fs and resultant MMF FR (or) rotor MMF Fr and resultant MMF FRI got this question by my school teacher while I was bunking the class.I'd like to ask this question from Production of Torque in Non-Salient Pole Machines in section Synchronous Machines of Electrical Machines
Answer» RIGHT answer is (d) stator MMF Fs and resultant MMF FR (or) rotor MMF Fr and resultant MMF FR For explanation I WOULD say: The ELECTRICAL space angle δs between Fs and FR ; and δr between Fr and FR are CALLED LOAD angles.
