1. Calculate the coil pitches and indicate the slots into which the first coils should be placed for the following armature windings: (a) 36 slots, four poles; (b) 57 slots, four poles; (c) 76 slots, six poles; (d) 132 slots, eight poles; (e) 270 slots, 10 poles; (f) 234 slots, 12 poles. 2. How many parallel paths are there in the armature windings of Prob. 1, if (a), (b), and (c) are simplex-wave wound and the others are simplex-lap wound?
