The phaseangle of said current wave is found from the reference pointwhich was set at zero degree of the open circuit wave. The wave form of under the similar conditionmay also be approximated by still another method. We have arelation between the induced and current as follows, where XA is the ohmic reactance of the armature which is notby any means a constant, but a careful measurement shows thatit is a function of the position of armature with referenceto the field magnets. Graph 5 shows the values of armaturereactance at various position of the armature. deducing the last equation similarly as the firstmethod, we get, the instantaneous values of e could easily be computed. In both of these methods ihe smaller the incrementsand^0 taken in the
