16. A 110 V, d.c. shunt generator delivers a load of 50 A. The armature resistance is 0.2 and field resistance is 55 . The generator is driven at 1800 r.p.m. It has 6 poles with 360 conductors connected in lap fashion. Calculate i) The no load voltage (ii) The flux per pole (Ans.: (i) 120.4 V (ii) 0.011 Wb) 17. A long shunt compound generator delivers a load current of 50 A at 500 V. It has armature, series field and shunt field resistance of 0.05 $2, 0.03 2 and 250 2 respectively. Calculate the generated c.m.f. (Ans.: 504.16 V) 18. A d.c. machine has 8 poles, lap connected armature with 960 conductors and flux per pole is 40 mWb. It is driven at 400 r.p.m. Calculate the generated e.m.f. If now lap connected armature is replaced by wave connected, calculate the speed at which it should be driven to generate 400 V. (Ans. 250 V, 156 r.p.m.)
