s in series, as also has the coil B.Suppose T produces 8 volts, the two coils T and B are inparallel and do not add their electro-motive forces. 1054 Steam Engineering The coils L and E are dead, L being in series with B andE in series with T^ but they produce no electro-motive force.At the present… … Fig. 447 it, is beginning to cut flux also. T is only % active, pro-ducing say 6 volts, and E is not totally dead but ^4 active,producing 2 volts. Hence the voltage of the machine isstill 8. At % revolution E is doing full work and B is dead andin series with it, while T is dead and L in series…
