A hlau tuaj yeem xa cov electrons thiab lub zogyog li nws tsis yog dielectric rau electrons.
Yuav ua li cas thaum hlau siv los ua dielectric?
Thaum cov dielectrics muab tso rau hauv qhov hluav taws xob, xyaum tsis muaj cov dej ntws hauv lawv vim, tsis zoo li cov hlau, lawv tsis muaj qhov xoob xoob, lossis dawb, cov hluav taws xob uas yuav ntws los ntawm cov khoom siv. … Hloov chaw, hluav taws xob polarization tshwm sim.
Cov khoom siv twg yog siv los ua qhov nruab nrab dielectric?
Hauv kev xyaum, feem ntau cov ntaub ntawv dielectric yog cov khoom. Piv txwv suav nrog porcelain (ceramic), mica, iav, yas, thiab cov oxides ntawm ntau yam hlauQee cov kua thiab roj tuaj yeem ua cov khoom siv hluav taws xob zoo. Cov huab cua qhuav yog ib qho zoo heev dielectric, thiab yog siv nyob rau hauv qhov sib txawv capacitors thiab qee hom kab sib kis.
Dab tsi yog dielectric ntawm qhov nruab nrab?
1. (General Physics) ib yam khoom lossis qhov nruab nrab uas tuaj yeem txhawb nqa hluav taws xob zoo li qub hauv nws. 2. (General Physics) ib yam khoom los yog lub cev ntawm hluav taws xob conductivity tsawg heev; insulator.
Dab tsi yog lub zog dielectric ntawm hlau?
Dielectric zog txhais tau tias yog lub zog hluav taws xob ntawm cov khoom siv thuamNyob rau hauv qhov hluav taws xob muaj zog txaus cov khoom siv hluav taws xob ntawm cov hluav taws xob insulator tawg cia kom ntws tawm. Dielectric lub zog yog ntsuas raws li qhov siab tshaj plaws voltage yuav tsum tau tsim ib tug dielectric tawg los ntawm ib tug khoom.
