currentmay be zero, in which case the curve is called the no-load saturationcurve, or sometimes the open-circuit characteristic curve. Observa-tions for a saturation curve may be taken with full-load currentin the armature; but this is rarely done, except in alternators ofcomparatively small… … cf e (wwnr\ RofentialTra nsformer. rig. 189.
