in the armature ofan alternating current generatorby the magnetic field of the polesystem, the vector I represents thecurrent flowing through the arma-ture and round the external circuit;this current is assumed to lag 45°behind OA. OB represents theelectromotive force induced in thearmature by the… … Fig- 235 244 Electrical Engineering resultant e.m.f. induced in the armature. This e.m.f. will be used up tosome extent i» overcoming the internal resistance of the armature; theproduct IRa will be in phase with the current and is shown in Fig. 235 asthe vector OC or ED.
