External characteristics is drawn with constant term/s ____________(a)

1.	External characteristics is drawn with constant term/s ____________(a) Field current(b) Speed(c) Both Field current and Speed(d) LoadThe question was asked by my college director while I was bunking the class.This intriguing question originated from External and Armature Characteristics of DC Generator topic in chapter DC Generator of DC Machines
Answer» Right answer is (c) Both Field current and Speed The explanation is: External characteristic is a load characteristic. In this, variation of terminal VOLTAGE ACROSS ARMATURE current is DRAWN keeping speed and field current constant. Load is generally KEPT variable.
