Current flowing through the armature conductors Ic is related to total current Ia by_______(a) Ic = A Ia(b) Ic = Ia/A(c) Ic = A^2 Ia(d) Ic = A/IaI got this question during an interview.Question is from Lap Winding topic in portion Armature Windings of DC Machines

Answer»

The correct option is (b) Ic = IA/A

The BEST I can explain: Two positive and two NEGATIVE BRUSHES are RESPECTIVELY connected in parallel for feeding the external circuit. As per the ring diagram Ia splits into the number of poles equally. Poles = Parallel paths. Thus, Ic = Ia /A.
