In a shunt wound DC motor, how is the shunt field connected?

Correct Answer: Option B — The shunt field is wired in parallel with the armature circuit, including armature, commutating, and compensating windings.

The shunt field circuit is connected directly across the supply voltage in parallel with the entire armature circuit, which includes the armature core, commutating poles, and compensating windings, ensuring constant excitation voltage regardless of changing armature load currents.
