Piv txwv ntawm cov conductors muaj xws li metals, aqueous solutions of s alts (ie, ionic compounds dissolved in water), graphite, and the human body. Piv txwv ntawm cov insulators muaj xws li yas, Styrofoam, ntawv, roj hmab, iav thiab cua qhuav.
Tus neeg xyuas pib piav qhia li cas?
Cov neeg siv khoom ua hluav taws xob 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 neeg coj 5 yam piv txwv yog dab tsi?
Cov khoom siv hluav taws xob zoo tshaj plaws yog:
- Silver.
- kub.
- Copper.
- Aluminium.
- Mercury.
- Steel.
- Iron.
- Seawater.
Tus neeg xyuas pib teb yog dab tsi?
Ib tug hluav taws xob conductor yog ib yam khoom uas cov khoom siv hluav taws xob, feem ntau cov hluav taws xob, txav tau yooj yim ntawm atom mus rau atom nrog daim ntawv thov voltage. Conductivity, feem ntau, yog lub peev xwm los xa ib yam dab tsi, xws li hluav taws xob lossis cua sov. … Tooj, hlau, kub, txhuas, thiab tooj dag kuj yog cov neeg coj zoo.
Yuav ua li cas hauv cov neeg ua haujlwm?
Ib tus neeg xyuas pib yog khoom uas muaj cov nqi hluav taws xob txav tau. Hauv cov khoom siv hlau, xws li tooj liab lossis txhuas, cov khoom txav tau them yog cov khoom siv hluav taws xob, tab sis nyob rau hauv lwm yam.rooj plaub lawv tuaj yeem yog ions lossis lwm hom tsiaj uas raug them zoo.
