Abstract:

Investigation of a spark, energized by a voltage source capable of supplying currents of several hundred amperes for a period of the order of 10 to the minus 8th power sec, showed that the voltage drop on the spark for such currents is considerably greater than the potential difference in a normal arc. By the end of the voltage dip, the diameter of the channel, determined by the Kerr cell, is independent of the current, at least in first approximation. There is a certain critical current density in the spark channel for the given potential difference between the electrodes. The quantity of energy liberated in the spark gap can be very large, owing to saturation. A discharge in metal-wire vapor is akin to a discharge with high current density in the last stage of the spark. Author
