e electro-motive force due to therotation passes throughits maximum. Thespeed of rotation and the resistance R between the points A andAj are so adjusted that the induced electromotive force is com-pensated by the difference of potential between the points A andAj As there is no current in the… … Fig. 327. 27r A 4:TrnjC = e, and if R is the resistance between the two points a and Aj we have,R e _8Tr^n-^A G T As in the preceding method, the current cancels out.
