Lub plhaub sab nrauv feem ntau yog cov yas insulator, thiab sab hauv yog tsim los ntawm cov hlau conductor, lub teeb me me thiab cov xaim hluav taws xob. Lub teeb me me yog ntim nrog cov roj tsis muaj xim tsis muaj xim (neon gas), uas tuaj yeem tsim lub teeb liab nrog kev sib kis tau zoo nyob rau hauv qhov kev zoo siab ntawm qhov hluav taws xob. Thaum cov khoom raug them, siv tus cwj mem hluav taws xob los ntsuas lub teeb neon kom tig liab, txwv tsis pub lub teeb neon yuav tsis teeb.
