Electrosurgery ua haujlwm los ntawm kev tsom mus rau qhov tam sim no (nce nws qhov ntom) ntawm cov khoom siv hluav taws xob kom tsim tau cov nyhuv thermal cov ntaub so ntswg thiab dispersing nws ntawm dispersive electrode los tiv thaiv cov ntaub so ntswg kub hnyiab. Cov nyhuv thermal yog ncaj qha proportional rau tam sim no ceev squared ([I / A] 2), cov ntaub so ntswg impedance (R) thiab daim ntawv thov lub sij hawm (T) - piv txwv li thermal nyhuv=(I / A) 2 × R × T, qhov twg A hais txog mus rau thaj tsam electrode. Txhawm rau ua kom cov nyhuv thermal, nws yog ib qho tseem ceeb kom tsis txhob muaj kev ntxias kom nce qib ESU wattage kom nce qhov tam sim no, uas yuav ua rau muaj kev pheej hmoo ntawm cov ntaub so ntswg uas tsis xav tau. Txo lub vojvoog ntawm cov khoom siv hluav taws xob los ntawm ib nrab tuaj yeem ua rau 16-fold nce hauv thermal hloov yam tsis hloov lub zog teeb. Kev hloov kho cov txheej txheem phais kom nce cov ntaub so ntswg impedance los ntawm kev tshem tawm cov kua dej xws li cov ntshav, compressing cov hlab ntsha lossis cov ntaub so ntswg stretching kuj ua rau cov thermal nyhuv yam tsis tas yuav ua kom lub zog.
