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.
