What reading level is Abc of the Telephone; a Practical And Useful Treatise for Students And Workers in Telephony, Giving a Review of the Development of the Industry to the Present Date book?
To quickly assess the difficulty of the text, read a short excerpt:
179 shows the circuits of a bridged telephone apparatus. As may be seen, the rising of the hook on the removal of the receiver, while it makes the circuit of the transmitter and receiver, does not break that of the bell and generator, which are left permanently bridged across the talking circuit. For this reason the switch lever makes no lower contacts. Two possible paths are thus presented to the telephone current: (a) that leading through the bell magnets to line, or (J)) that leading direct ...to line. It chooses the latter path, as being the line of least resistance.
Similarly a current on the line will enter an apparatus in which the telephone circuit is made, and will avoid the path leading through the coils of the bell magnets, which are bridged across.
Wiring of a Bridged Line. — As may be seen from a brief examination of Fig. 178, a complete circuit may be formed between any two apparatus in the system without reference to any of the others. Thus, if the telephoner at the second station is conversing with the one at the third, the current passes out from the right-hand binding post of his apparatus, PARTY LINES.
