The resistance of armature winding depends on

Correct answer: D. all of the above

  • A. length of conductor
  • B. cross-sectional area of the conductor
  • C. number of conductors
  • D. all of the above

Explanation

From R = ρL/A, resistance increases with conductor length and decreases with cross-sectional area; the number of conductors affects the total effective length of the winding. Therefore all three listed factors matter.
