A shunt dynamo has an armature resistance of 0.120 . (a) If it is connected across 220-V

Question:

A shunt dynamo has an armature resistance of 0.120 Ω.

(a) If it is connected across 220-V mains and is running as a motor, what is the induced (back) emf when the armature current is 50.0 A?

(b) If this machine is running as a generator, what is the induced emf when the armature is delivering 50.0 A at 220 V to the shunt field and external circuit?
