What reading level is Manual of Wireless Telegraphy for the Use of Naval Electricians book?
To quickly assess the difficulty of the text, read a short excerpt:
Suppose a spark gap set to break down at a potential of 10, 000 volts, to be used in a circuit where the maximum potential reached in the condenser is 30, 000 volts.
Let the curve of sines in fig. 18 represent the condenser potentials of the oscillating circuit during 2 alternations, each lasting y^ of a second.
The resistance of the spark gap is practically infinite before the poten- tial reaches 10, 000 volts, and therefore no current passes. When the potential has risen to 10, 000 volts the ...spark gap is ruptured. Its resist- ance decreases instantly to a fraction of an ohm, and during the first half of the oscillation the condenser is discharged to zero potential. Dur- ing the last half of the oscillation it is charged again in the opposite sense. The sparks pass first in one direction and then in the other, and the spark gap not regaining its resisting qualities, the oscillations or surgings continue until the potential (owing to losses due to the radiation of energy in the shape of electric waves, to heating the circuit, and the light and heat at the spark gap) does not rise high enough to disrupt the gap.
