Question: What is the formula for the armature resistance in PMDC motor?
Options
A : armature resistance = (Diameter + length)*total number of armature conductors/1.2 * 104 * number of parallel paths in the armature2
B : armature resistance = (Diameter + length)*total number of armature conductors*1.2 * 104 * number of parallel paths in the armature2
C : armature resistance = (Diameter + length)*total number of armature conductors/1.2 * 104 + number of parallel paths in the armature2
D : armature resistance = (Diameter + length)+total number of armature conductors/1.2 * 104 * number of parallel paths in the armature2
