WebA phasor diagram by itself is meaningless. The value of the emf acting from Y via N to R is the phasor difference of E NR and E NY. Hence E YN is drawn equal and opposite to E NY and added to E NR, giving E YNR as the emf acting from Y to R via N. Note that the three subscript letters Y NR are necessary to indicate unambiguously the positive ... WebThe C-EMF traces a circular path as it moves from the original condition to the reduced load, and the constant-power line at the new operating point is half as high as the original constant- power line. FIGURE 3: Phasor …
