Abstract
Voltages from 10-14,000 V demonstrate currents up to 70 A with resistances of .apprx. 200 .OMEGA. in studies in hogs. Below 1000 V, a current reduction is observed following arcing and skin necrosis. At the higher voltages this phenomenon was not observed. The energy required for tissue damage was dependent upon the voltage and time of application. The tissue electrode resistance with stainless steel discs was proportional to the diameter. Skin burning commenced at the periphery of the electrodes and moved inward. For application of currents between the hindlimbs of the hog, the current per tissue cross-section was greatest in artery and nerve, followed by muscle, fat, bone marrow and bone cortex.
