TitlePaper, 'Specific inductive capacity [dielectric constant]' by J [John] Hopkinson
Date1887
DescriptionHopkinson writes: 'The experiments which are the subject of the present communication were originally undertaken with a view to ascertain whether or not various methods of determination would give the same values to the specific inductive capacities of dielectrics. The programme was subsequently narrowed, as there appeared to be no evidence of serious discrepancy by existing methods. In most cases the method of experiment has been a modification of the method proposed by Professor Maxwell, and employed by Mr Gordon. The only vice in Mr Gordon’s employment of that method was that plates of dielectrics of dimensions comparable with their thickness were regarded as of infinite area, and thus an error of unexpectedly great magnitude was introduced.'

Annotations in pencil and ink. Includes three circuit diagrams.
