Hauv kev tiv thaiv kev ntsuas ntawm cov khoom siv hluav taws xob rwb thaiv tsev, kev ntsuas lub sijhawm ntawm cov roj insulating ntawm cov khoom siv hluav taws xob yuav tsum tau ua.Kev ntsuas ntawm dielectric poob thiab resistivity ntawm cov roj insulating yog ib qho tseem ceeb tshaj plaws.Tau ntev, feem ntau ntawm lawv tau raug ntsuas los ntawm tus choj txoj kev, uas yog cumbersome rau kev khiav hauj lwm, thiab kev ntsuas qhov tseeb yog cuam tshuam los ntawm ntau yam, ua rau muaj kev ntsuas loj..
