摘要:
Electrostatic problems in connection with two unequal parallel cylinders, and with single-core cables when the axes of the cores are parallel but not coincident with the axes of the outer cylinders, are considered. The solutions are given by formulae the numerical value of which can be readily evaluated. Novel relations are given connecting the capacity between any two cylinders with the capacities between two equal cylinders and with the capacities of cylindrical condensers.

摘要:
In this paper the use of “circuit constants” for the calcualtion of transmission-line problems is dealt with in an elemetary way, in the hope that many who perhaps would not have the time or patience to follow the original papers of Messrs. Evans and Sels may be encouraged to use their very powerful and useful methods.To avoid having to refer to textbooks for the elements of complex algebra, a few notes on its use have been included.The formulae for calculating the constants of series and parallel circuits are developed; and the determination of the particular values of the constants for transmission lines, and for transformers, is dealt with in detail.Following this, methods for dealing with more complex cases of lines supplying more than one substation, and branching lines, are dealt with. An actual example of an existing transmission line is worked out in detail.

摘要:
The paper describes the researches which have been carried out at the National Physical Laboratory for the Radio Research Board. A standard method of testing the amplification and input impedance of an amplifier is described, and the theory of the load introduced by the amplifier as well as by reaction is shown to agree with the observed results.Some preliminary experiments on distortion are described, output wave-forms from audio-frequency amplifiers being analysed.
