Assume that a separately excited shunt de machine has a rated terminal voltage of 230 V and a rated armature current of 100 A. Its armature winding resistance, commutating winding resis- tance, and compensating winding resistance are 0.08. 0.01, and 0.008 52, respectively. The resis- tance of external wires (i.e.. R.) is 0.0022. Determine the following: (a) The induced armature voltage if the machine is operating as a generator at full load (b) The induced armature voltage if the machine is operating as a motor at full load

![Assume that a separately excited shunt de machine has a rated terminal voltage of 230 V and a
rated armature current of 100 A. Its armature winding resistance, commutating winding resis-
tance, and compensating winding resistance are 0.08, 0.01, and 0.00842, respectively. The resis-
tance of external wires (i.e., R…) is 0.00242. Determine the following:
