Fig. 9 Group III—Components of transmitting and assumed mesh currents 250 BELL SYSTEM TECHNICAL JOURNAL when transmitting (see Fig. 5 of Group III), it will be looked upon asthe same passive impedance in tandem with an impedanceless generatorwhose equals the variations in voltage drop (of the battery sup-ply current) across the transmitter due to the changes in its impedancewhich occur when the transmitter is agitated by sound. This replaces in the circuit the sound engendered variations in thetransmitter impedance, thereby permitting this impedance to betreated as a constant. Being impedanceless, this generator may,without effect upon the circuit, be replaced by two impedancelessgenerators—each having the same as the first—connected inparallel as shown in Fig. 6. The direct connection between pointsa and h, however, is shunted by the impedanceless path acb, so that thedirect connection ah may, without effect, be broken as in Fig. , the tw
