Cov khoom siv hluav taws xob tau yooj yim heev vim lawv cov hluav taws xob dawb. Insulators tiv thaiv hluav taws xob tam sim no thiab ua rau cov neeg ua haujlwm tsis zoo. Qee cov khoom siv feem ntau yog tooj liab, txhuas, kub, thiab nyiaj. Qee cov insulators feem ntau yog iav, cua, yas, roj hmab, thiab ntoo.
Cov qauv coj ua thiab cov insulators yog dab tsi?
Ib tus neeg xyuas pib yog cov khoom siv uas pab tau yooj yim ntawm hluav taws xob los yog cua sov. Piv txwv li: tooj, nyiaj, kub. Ib qho insulator yog cov khoom siv uas tsis tso cai rau qhov yooj yim ntawm hluav taws xob los yog cua sov. Piv txwv li: ntawv, ntoo, roj hmab.
insulator lossis conductor nyob qhov twg?
Cov khoom uas muaj hluav taws xob siab (ntau cov hluav taws xob dawb) yog hu ua conductors, thaum cov khoom uas muaj hluav taws xob qis (tsawg lossis tsis muaj hluav taws xob dawb) yog hu ua insulators. Nov yog ob peb yam piv txwv ntawm cov conductors thiab insulators: Tus neeg xyuas pib: nyiaj.
