Nyob hauv ntau cov ntaub ntawv, cov electrons nruj nreem khi rau cov atoms. … Feem ntau cov hlau, txawm li cas los xij, muaj cov hluav taws xob uas tuaj yeem tshem tawm ntawm lawv cov atoms thiab zip ib ncig Cov no yog hu ua dawb electrons. Cov hluav taws xob xoob ua kom yooj yim rau hluav taws xob ntws los ntawm cov ntaub ntawv no, yog li lawv paub tias yog hluav taws xob conductors hluav taws xob conductors Hauv physics thiab hluav taws xob engineering, tus neeg xyuas pib yog ib yam khoom lossis hom khoom uas tso cai rau tus nqi ntws. (hluav taws xob tam sim no) nyob rau hauv ib los yog ntau tshaj cov lus qhia … Insulators yog cov khoom uas tsis yog-conducting nrog ob peb mobile nqi uas txhawb tsuas insignificant hluav taws xob tam sim no. https://en.wikipedia.org › wiki › Electrical_conductor

Vim li cas cov conductors muaj dawb electrons?
Vim tias cov hluav taws xob tsis muaj zog rau cov nucleus zoo, lawv muaj kev ywj pheej txav mus los. Yog li ntawd, cov electrons hauv ib tus neeg xyuas pib tuaj yeem txav mus los yam tsis muaj kev txwv ntau thaum lub chaw hluav taws xob tsim hauv tus neeg xyuas pib. Tam sim no, peb paub tias cov electrons muaj kev ywj pheej txav mus rau hauv tus neeg xyuas pib.
Yuav ua li cas pub dawb electrons coj hluav taws xob?
Lub zog yuav tsum ua kom cov hluav taws xob dawb mus ncig ib qho kev taw qhiaIb lub xov tooj hluav taws xob (feem ntau hu ua lub roj teeb) tuaj yeem muab lub zog no thiab ua kom cov hluav taws xob dawb txav mus rau hauv cov hlau txuas nrog. nruab nrab ntawm nws ob lub terminals. Electrons ntws los ntawm qhov tsis zoo davhlau ya nyob twg los ntawm tus neeg xyuas pib mus rau qhov zoo davhlau ya nyob twg.
Vim li cas mobile electrons ua hluav taws xob?
Nws yog qhov kev txav dawb ntawm cov hluav taws xob hauv cov hlau uas muab lawv cov conductivity. … Thaum siv hluav taws xob hluav taws xob, hluav taws xob hauv cov hlau ua rau lub zog ntawm cov hluav taws xob, ua rau lawv hloov ntawm ib kawg mus rau lwm qhov kawg ntawm tus neeg xyuas pib. Cov hluav taws xob yuav txav mus rau qhov zoo.
hlau puas muaj hluav taws xob?
Hlau ua hluav taws xob los ntawm tso cai rau cov hluav taws xob dawb txav ntawm cov atoms. … Yog hais tias muaj tsawg zog hloov ntawm atoms, muaj tsawg conductivity. Cov nyiaj ntshiab thiab tooj liab muab qhov zoo tshaj plaws thermal conductivity, nrog aluminium tsawg dua.
