The variation in terminal voltage of DC shunt generator with respect t

1.	The variation in terminal voltage of DC shunt generator with respect to variation in separately excited DC generator is ___________(a) Much rapid(b) Much slower(c) Remains constant(d) Can’t sayI got this question during an interview for a job.The above asked question is from Characteristics of Separately Excited Generators topic in chapter DC Generator of DC Machines
Answer» The correct option is (a) MUCH rapid To explain I WOULD say: The terminal voltage DROPS off much more rapidly with load in a shunt generator than in a separately-excited generator because of fall in field current with terminal voltage. The EXTERNAL characteristic is a double-valued curve with a certain IL (MAX).
