Tsab xov xwm hais txog Lub Txhais ntawm capacitor
Lub ntsiab lus ntawm capacitor yog ib lub cuab yeej uas khaws cov nqi hluav taws xob thiab lub zog hluav taws xob. Lub capacitor yooj yim muaj ob daim hlau lossis cov ntawv uas muab tso ze ua ke tab sis tsis kov ib leeg thiab raug sib cais los ntawm lub insulator lossis lub tshuab nqus tsev. Cov conductors yog cov ntaub ntawv uas tuaj yeem ua hluav taws xob xws li hlau, thaum cov insulators yog cov ntaub ntawv uas tsis tuaj yeem ua hluav taws xob xws li yas.
Thaum xub thawj, ob lub conductors tsis muaj hluav taws xob them lossis tsis muaj hluav taws xob nruab nrab. Yuav kom ib lub conductor muaj hluav taws xob zoo thiab lwm lub conductor muaj hluav taws xob tsis zoo, ces yuav tsum muaj kev hloov pauv ntawm cov electrons los ntawm ib lub conductor mus rau lwm lub. Cov electrons nyob rau ntawm qhov chaw ntawm lub atom, yog li lawv yooj yim txav mus los. Tom qab cov electrons tau tsiv los ntawm ib lub conductor mus rau lwm lub, ib qho ntawm cov conductors muaj ntau dhau ntawm cov electrons (tsis muaj protons)
yog li ntawd nws thiaj li raug them tsis zoo, thaum lwm tus neeg coj hluav taws xob muaj qhov tsis txaus ntawm cov hluav taws xob (proton ntau dhau) yog li nws thiaj li raug them zoo. Ib qho kev piav qhia ntxaws txog cov txheej txheem ntawm kev them cov nqi hluav taws xob ntawm cov capacitors tau tshuaj xyuas txog lub ntsiab lus ntawm kev khaws cia lub zog hluav taws xob hauv cov capacitors.
Raws li tau piav qhia hauv daim duab ntawm ib sab, ib daim phaj ntawm cov hlau lead muaj hluav taws xob zoo (+Q) thaum lwm daim phaj ntawm cov hlau lead muaj hluav taws xob tsis zoo (-Q). Lub zog hluav taws xob hauv txhua daim phaj yog sib npaug tab sis muaj lub cim sib txawv kom tag nrho lub zog yog xoom (QQ = 0). Qhov muaj lub zog hluav taws xob nrog tib qhov loj me thiab lub cim sib txawv ntawm txhua daim phaj ua rau muaj qhov sib txawv ntawm ob daim phaj. Tus hlau lead uas muaj hluav taws xob zoo muaj lub zog hluav taws xob siab dua, thaum tus hlau lead uas muaj hluav taws xob tsis zoo muaj lub zog hluav taws xob qis dua. Hauv lwm lo lus, muaj lub zog hluav taws xob ntawm ob daim hlau lead uas muaj hluav taws xob, qhov twg qhov kev taw qhia ntawm lub zog hluav taws xob yog los ntawm lub zog hluav taws xob zoo mus rau lub zog hluav taws xob tsis zoo. Raws li tau tham txog hauv lub ncauj lus ntawm lub zog hluav taws xob, yog tias muaj lub zog hluav taws xob lossis qhov sib txawv ntawm lub zog hluav taws xob ntawm ob daim phaj ntawm cov hlau lead, yuav tsum muaj lub zog hluav taws xob hauv ob daim phaj.
Lub zog muaj peev xwm yog lub peev xwm ua haujlwm. Yog tias lub capacitor khaws lub zog muaj peev xwm hluav taws xob, lub capacitor tuaj yeem ua haujlwm. Qhov tseeb, capacitors muaj ntau yam kev siv hauv lub neej txhua hnub. Capacitors yog ib qho ntawm cov khoom tseem ceeb hauv cov hluav taws xob circuits, qhov twg cov hluav taws xob circuits yog lub hauv paus ntawm ntau yam khoom siv hluav taws xob.
