ion, and they can be added numerically only when theyare in phase with each other, as in the case of direct currents. 3857. As an example of the addition of two alternatingcurrents, suppose a divided circuit as shown in Fig. 1441.The main circuit 1 is divided into the branches 2 and 3, andampere… … Fig. 1441. would not be the case if an alternating current were flow-ing, unless the currents in the two branches happened tobe exactly in phase.Generally speaking,they would not beinphase, and the read-ing of A^ would beless than the sum ofA^ and A^. Therelation betweenthe three currentswould be…
