DISCOVERY OF THE OSCILLATORY EFFECT OF A SPARK DISCHARGE
Abstract and keywords
Abstract (English):
The history of the discovery of the oscillatory discharge of a capacitor is presented. The theory of the discharge of the condenser W. Thomson and the experimental justification of the oscillatory nature of the electric discharge by W. Feddersen are considered. The periods of electric oscillations calculated according to the theory of W. Thomson and obtained in the experiment are compared. Attention is paid to an oscillatory spark discharge arising in an oscillatory circuit with a spark gap. Rozhansky’s formula is given to determine the period of electric oscillations in such a circuit. The spark gap became the main source of radio waves in the initial period of development of wireless telegraphy.

Keywords:
spark, spark discharge, oscillatory discharge of a capacitor, formula by W. Thomson, damped oscillatory process, W. Feddersen’s experiments, spark gap, Rozhansky formula, silver electrodes
