Extracted text: In a d.c generator flux is directly proportional to L2 times field current.The generator is working at a speed of 200 r.p.m. and flux per pole is 30 mWb.f the generator is lap wounded with 600 conductors in series, find the e.m.f. generated. If the winding is wave wound, find the change in excitation current to obtain the same voltage as above. Number of poles in machine are 6.
