Ashunt wound
Bcompound wound with long shunt
Cseries wound
Dcompound wound with short shunt
AI Explanation

The correct answer is C) series wound. The wiring diagram in figure "C" of illustration EL-0054 represents a series wound DC motor. In a series wound motor, the field winding is connected in series with the armature winding, forming a single circuit. This configuration allows the motor to develop high starting torque, which is a desirable characteristic for many applications. The other answer choices are incorrect because: A) a shunt wound motor has the field winding connected in parallel with the armature, B) a compound wound motor with long shunt has the field winding connected in parallel and series with the armature, and D) a compound wound motor with short shunt has the field winding connected in series and parallel with the armature.
