Fulguration
Fulguration results from the action of electrical arcs striking the tissue at widely divergent locations, producing a high localized instantaneous current density, but a low average current density. The characteristics of fulguration are the superficial nature of the tissue destruction, and the presence of large amounts of carbonization. The latter effect is due to the high temperature of the tissue at the point of the arc strike. The former occurs because, after the arc strikes, current is dispersed widely, causing rapid diminution of current density and little generation of heat in the deeper structures. The thin layer of carbon and the desiccated tissue beneath it form an insulating barrier, decreasing the probability of subsequent arc strikes in the same location. Fulguration requires low amperage and high voltages to overcome the resistance of the large distances between electrode and tissue.
