Explanation of the Joshi Effect

Abstract

THE interesting experiments of Joshi and co-workers, on what they call the new light effect, relate to the decrease of current flowing in the high-voltage exciting circuit of a Siemen's ozonizer, when radiations fall on the chlorine gas contained within the ozonizer. Alternating voltages of the order of 10 kV. are applied between the inside and outside walls of the ozonizer and the current is measured, its order of magnitude being about 50 microamperes. The experimental arrangement and the description of the effect are given in recent papers by Deo¹ and Joshi².
