Страница 168 - Closer study of the two paths of discharge showed that the oblique arc left the very apex of the point, swinging out laterally into its path ; also that the normal arc, on approaching the point, avoided the apex and entered the wire from the side, never passing in at the point itself. From these observations it appears : — 1. That the discharge from the ball (positive) leaves the latter in a direction normal to the surface, but that it enters the other terminal at some distance from the apex. 2....
