What reading level is Wireless Telegraphy book?
To quickly assess the difficulty of the text, read a short excerpt:
283.
In each period, T, there are two different portions, viz. , the subperiod, Ti, called the "discharging stage, " during which the arc burns (7 is not zero), and the subperiod, T 2, the "charging stage, " during which the condenser acquires its charge, the arc being extinguished and the current / = 0.
During the first subperiod, TI, the curve of the current, /i, in the con- denser circuit is part of a sine curve* i. E. , we have an ordinary alter- nating current. During the second portion, T... 2, the current is a direct current /i = IQ. The voltage, V, across the condenser coatings varies correspondingly: during 7\ it is oscillatory, during Tz it rises from the value F a, at which the arc was extinguished, to the value, V 2) at which it is again ignited, rising approximately in a straight line. F The voltage, F, across the arc falls abruptly from the value, V z, which it has at the moment of ignition, to the value, F&, which it has during the t \ ^4- ^ _^ *o J r o 7 +/]^/ V t 1 o /j, I FIG.
