Answer» RIGHT answer is (a) NUMBER of turns per COIL = number of conductors/2coils/slotnumber of ARMATURE teeth Best explanation: The number of conductors is CALCULATED along with the coils per slot is calculated. Next, the number of armature teeth is calculated, and on substitution gives the number of turns per coil.
