Abstract

Electrical Oscillation Experiment was as shown. [drawing opposite page of apparatus] distance between primary & secondary sparks 10 cms In the 1st trial with the two glass rods at an angle of 165[degree sign] and converging towards primary spark, the distance between them being 0.2 cms. The number of sparks passing during 25 primary makes and breaks was 50 unscreened and 1 screened.##On making the angle 180[degree sigh] and keeping the same distance the number of unscreened sparks was 47 of screened 2##On making the angle 143[degree sign] diverging from the primary spakr the number of uscreened sparks was 25 of screened 0.##Cleaned the surface of the electrodes and repeated last trial with the distance between them 0.17 and the angle 143[degreee sign] the number of unscreened sparks 43 and the screened 45.##With the angle of 147[degree sign] and the same distance the number of unscreened sparks 28 and screened 299.##The platinum wires were then drilled out for a distance of about 0.05 cm with a meedle drill, so that they were certain to be screened at their extremeties from direct radiation. At a distance of 27 cms from the primary spark the results were:-- [CONTINUE TEXT]
