TitleUnpublished paper, 'On current curves' by R L [Richard Lionel] Hippisley
CreatorHippisley; Richard Lionel (1853-1936); member of the Royal Engineers; Director of Telegraphs in South Africa during the Second Boer War
Date[1892]
DescriptionThe object of the present paper is to show how to determine expressions for the current in circuits having iron cores, similar to the well-known equations i = E/R (1 ‒ e^[-Rt/L]) and i = E/√(R^2 + p^2 L^2) sin (pt ‒ θ) for circuits without iron, which will enable the current curves to be pre-determined by calculation and plotted independently of experiment.

Annotations in pencil and ink throughout.
