Hlau xws li tooj liab typify conductors, thaum feem ntau cov khoom tsis yog xim hlau tau hais tias yog cov insulators zoo, muaj kev tiv thaiv siab heev rau kev ntws ntawm cov nqi los ntawm lawv. "Conductor" txhais tau hais tias sab nraud electrons ntawm lub atoms yog xoob khi thiab txav mus los ntawm cov khoom.
Puas conductors muaj dawb electrons?
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 neeg siv khoom siv yog tooj liab, txhuas, kub, thiab nyiaj.
Yuav ua li cas tus neeg xyuas pib?
Cov khoom siv yog cov khoom uas tso cai rau cov hluav taws xob ntws tawm ntawm cov khoom mus rau cov khoom. Ib yam khoom uas ua los ntawm cov khoom siv yuav tso cai rau kev xa mus thoob plaws tag nrho cov khoom nto.
Puas muaj pes tsawg electrons nyob rau hauv ib tug conductor?
Nco ntsoov tias tus neeg xyuas pib zoo muaj 1 valence electrons thiab ib qho insulator muaj yim valence electrons. Lub semiconductor muaj 4 valence electrons.
Puas yog tooj liab yog tus neeg xyuas pib lossis insulator?
tooj liab yog tus neeg xyuas pib zoo heev, thiab cov yas yog cov rwb thaiv tsev zoo heev. Thaum muaj ntau tshaj ib qho khoom siv rau hluav taws xob tam sim no ntws los ntawm, qhov tam sim no ib txwm taug kev los ntawm cov khoom siv nrog qhov tsawg kawg nkaus.
