Active Electrode Surface Area
High current density: the active electrode has been decreased to 1cm2, raising the current density at this site to 100W/cm2. Now there will be a rapid rate of temperature rise—quickly with a thin-wire electrode (cutting results) and less quickly with a br
Energy Sources Used in Laparoscopy
Low current density is depicted schematically by showing an active electrode with a large surface area (low density of current in the larger surface area). The amount of current going through the patient at this electrode is only 1 Watt/cm2. Heating th
