An electric motor connected to a 120 V DC network with a total circuit resistance of 20 ohms transmits 160 watts of power to the drive under a certain load. Which e. d.s. will the same motor develop if it were used as a dynamo, rotating the armature with the same angular velocity that it had when working as a motor? What is the meaning of the ambiguity of the obtained result?
