This results in a fourfold increase of heat Correspondingly, heat drops by 75% if current density is reduced by half, e. g. by doubling the effectiveelectrode contact area.
相应地，如果将有效的电极接触面积加大一倍，电流密度将减少一半，热量则减少75%。

Doubling hf-current results in a doubling of current density and a fourfold heat provided that the area of effective contact between the tissue ang the electrode remains constant.
