What reading level is American Telegraph Practice a Complete Technical Course in Modern Telegraphy book?
To quickly assess the difficulty of the text, read a short excerpt:
, while the other terminal of the battery and the other end of the line are grounded (Fig. 68) it may be shown that when the key K is closed, current traverses the entire circuit almost instantaneously, affecting the distant end 90 AMERICAN TELEGRAPH PRACTICE of the conductor at nearly the same instant that the key is closed. The first indication of electrification at the distant end, however, is quite feeble, but the current strength increases gradually until maximum value obtains. If a curren...t-indicating meter be inserted at the distant end of the line, there will be no deflection of its pointer until the current has attained a strength sufficient to energize the coils of the instrument thereby causing the indicating needle to move from its position of rest. The more sensitive the instrument employed for the purpose, the earlier will be the indication of current passing through it.
K FIG. 68.
1 After the first movement of the needle has been observed, the amount of deflection will increase gradually until when maximum current obtains at the distant end, the pointer will have moved to a definite position, distant from its position of rest.
