In order to analyzing the influents of length, width, height and effectivecontactarea per unit volume, three kinds of fills whose character are different selected as experiment speriment.
Doubling hf-current results in a doubling of current density and a fourfold heat provided that the area of effectivecontact between the tissue ang the electrode remains constant.
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 effective electrode contactarea.
