Investigation of Voltage Drop across Reactance of Expanding Spark Channel

A voltage drop across reactance of an expanding spark channel was numerically studied in the paper. Changes in the discharge current and radius of the conductive spark channel over time were determined by the spark expansion simulation. This data was used to calculate changes in channel inductance and voltage drop across the reactance of a spark. The analysis of the influence of energy stored in the channel inductance on the measurement of the discharge energy dissipated in the spark was carried out.
