24 ELECTRICAL ENGINEERING PROBLEMS 



8. By test a bipolar shunt generator gives 90 volts and 25 

 amperes to the outside circuit; if the resistance of the armature 

 be 0.324 ohms, the resistance of the field be 41.0 ohms, required 

 the current through the armature conductor and the B. & S. size 

 if 500 circular mils per ampere be used. Also the total e.m.f. 

 generated by the armature. (2 min.)
