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.
