A periodic phenomenon has been observed in the current pulses in terms of counts with time of exposure during non varient nature of the field gradient through air in a Siemen's type ozonizer. The dark counts, presented in the plots, at a temperature of 50 degree calcius for pulses of 5 and 50 V are initially large at the first instance of recording and then decrease rapidly. The theoretical explanation for the various observed features has been attempted on the basis of the formation of the charge inequality and equality conditions in a plasma
