n onedirection ; if one lies above and the other below O, it isin the other direction^ whilst it is zero at anj time thateither e or i changes sign. The question we have toinvestigate is : at what phase during the cycle is theproduct O A X O B Si maximum, and what is the relationbetween this… … never change sign, and its maximum will be propor-tional to 215,000. When the generator is working onshort circuit, the lag 4^ between e and i is known fromthe relation that e,: e^=l : 4, to which corresponds \p = 76°.Let the phase for which the diagram is drawn be repre-sented by the angle a, then…
