Current Flow in Rectangular Conductors

Abstract

THE simplest case of current flow in two dimensions is that of electricity flowing across a rectangular plate the two opposite sides of which are the electrodes.I am, however, unacquainted with any formula dealing with the cases in which the electrodes do not extend over the whole of these .sides,and it is difficult to see how any approximation based on a jniori reasoning can be made for these cases.By the use of Schwarz's transformation, however, the results come out in a very simple manner.
