The calculation of the electric field for an infinite dielectric plate between two spherical electrodes

  By considering the equipotential surfaces round two equal and opposite point charges, the electric field for an infinite dielectric plate between two spherical electrodes has been calculated. The solution is given as an infinite series in terms of applied voltage, radius of the electrodes, thickness of the dielectric plate, and permittivities of the plate and the medium. Curves have been derived to show the significance of the dependence of the voltage gradient in the field on the ratio of the plate thickness to the electrode diameter, and the ratio of the permittivity of the plate to that of the medium. The edge effect in the electrical breakdown of solid dielectrics may be attributed to the discharge in the medium, which occurs when the voltage gradient on the electrode surface reaches a value favourable to its breakdown condition.
Limits of accuracy in resistance measurement

  The resolution that can be achieved in resistance measurement is shown to be limited by the amplitude of thermal noise relative to the input power of the resistance. The errors of measurement due to resolution and power loading are analysed and the minimum value of their sum is found to be proportional to the cube root of the circuit and detector noise factors, the detector bandwidth and the loadcorrection error. The noise factors of some common circuit arrangements are evaluated and the other errors of measurement in addition to resolution and power-loading errors are discussed. The total error is shown to have a limiting value near 1 part in 10⁸ for existing high-quality standard resistors and this is illustrated by a practical example.
An alternating-current analogue of the Kelvin double bridge

  In connection with a project for an absolute determination of the ohm, the author has developed an a.c. 4-terminal resistance bridge. This new bridge is analogous to the Kelvin double bridge, but resistive ratio arms are replaced by transformer ratio arms and inductive dividers. Besides the benefits of impedance matching and ease of amplification which the use of alternating current confers, the replacement of resistive ratios by inductive devices brings great advantages in accuracy and stability of ratio. In the bridge described here, the ratio is believed to depart from the nominal value of 10: 1 by little more than 2 parts in 10⁷ over the frequency range of 330 rad/s (52.5 c/s) to 33000 rad/s (5.25 kc/s).

  High-sensitivity feedback relay amplifiers may be built with a hysteresis relay. It is possible to obtain a linear range which is not large compared with the hysteresis band. The design of these amplifiers is accomplished using the exponential input describing function. The accuracy of this design method is confirmed by experiment.
Prediction of the time/current characteristics of a long cartridge fuse with a single-wire element

  Numerous forms of solution for the electro-thermal equations of fuses, together with various methods for establishing the parameters of these equations, have been attempted. Following earlier work on the analytical determination of the characteristics of semi-enclosed oil-immersed fuses and short fuses enclosed in silica or quartz filler, a new method has been established for the solution of long cartridge fuses. This new method is simple and based on a tabular technique derived for the work of Jaeger and Newstead on the transient heating of buried cables.The paper gives a brief treatment of the heat equations for a fuse and indicates the point of departure from the method previously adopted by Guile. The method of solution is indicated and tabular solutions are given for three particular cases of fuse elements of different cross-sections. The predicted and experimentally determined time/current characteristics are shown to be in close agreement.
