The results of experimental studies on the effect of the length of the discharge gap in an underwater spark discharge and the length of a metallic conductor during its underwater electrical explosion are presented. It is noted that in both cases the dependence of the amplitude of the pressure wave on the length of the interelectrode gap or the length of the conductor has an optimum at which the pressure wave with the maximum amplitude is generated. In this regard, it is necessary to strive to implement modes with a given optimum value of the length of the interelectrode gap, which provides an effective electrical discharge effect on the processing object and with an underwater spark discharge also allows for a near-critical mode, which positively affects the life and durability of electrical discharge equipment. The results of experimental studies also showed that a change in the length of a metallic conductor during its underwater explosion with unchanged parameters of the discharge circuit leads to a change in the mode of the underwater electrical explosion of a conductor.
