A. Starting torque of series motor is considerably greater than shunt motor
B. Armature is the rotating part of DC generator
C. In series motor, the field is connected in series with armature
D. Series motors are not suitable to drive devices which must run at high speed at light loads.
E. In shunt motor, torque is independent of armature current.
Choose the correct answer from the options given below:

Show Hint
To easily identify incorrect statements:
Torque in any DC motor is given by \(T \propto \Phi I_a\). Since \(I_a\) is the current driving the motor, torque can never be independent of the armature current, which immediately rules out Statement E.
Torque in any DC motor is given by \(T \propto \Phi I_a\). Since \(I_a\) is the current driving the motor, torque can never be independent of the armature current, which immediately rules out Statement E.
