In a A.C. series motor armature coils are usually connected to commutator____________?
Correct answer: A. through resistance
- A. through resistance
- B. through reactances
- C. through capacitors
- D. solidly
Explanation
AC series motors have poor commutation because of reactance, so resistance is commonly included in the armature-coil connections or leads to improve commutation. Direct solid connection would not provide this sparking-reduction benefit.
