find the output as a function of the electrical quan-tities. For this purpose, we multiply equation (99) by /^ and get V.I, = E.I, + I,\R, (102). The product V.I a is the total power transmitted to the armature, •while la^.Ra is the power dissipated as heat due to the armature resistance. Hence,… … Fig. 186 Fig. 187 It is possible for us now to compare the two expressions found for theoutput. Equating them, we have E.I, = Mi.27r.n.9-8i {103). If we substitute for E and M^ the values found for them in equations (79)and (98), we shall find that both sides of our equation are identical. When we…
