Thaum siv lub dielectric, khoom nruab nrab ntawm cov paib sib npaug ntawm lub capacitor yuav polarize… Thaum kawg txhua yam khoom muaj "dielectric breakdown point," uas qhov sib txawv yuav dhau los. siab dhau rau nws insulate, thiab nws ionizes thiab tso cai rau txoj kev tam sim no.
Yuav ua li cas thaum lub dielectric ntawm lub capacitor tawg?
Cov hluav taws xob tawg yuav tshwm sim yog tias qhov hluav taws xob siv rau lub capacitor siab dhau. Lub thickness thiab hom khoom siv cuam tshuam rau kev ua haujlwm voltage ntawm lub capacitor.
Yuav ua li cas thaum dielectric tawg tshwm sim?
Dielectric breakdown yog tsis ua haujlwm ntawm cov khoom siv insulating los tiv thaiv kev ntws ntawm tam sim no raws li kev siv hluav taws xob ntxhov siab. Lub zog tawg yog qhov hluav taws xob uas qhov tsis ua haujlwm tshwm sim, thiab cov khoom siv tsis yog hluav taws xob rwb thaiv tsev lawm.
Thaum lub capacitor dhau qhov kev tawg ntawm dielectric?
Nqe Lus Nug: Lub tshuab hluav taws xob siab uas them cov phaj sib txuas ua ke tau dhau qhov dielectric tawg: nws cov yeeb yaj kiab dielectric tsis tuaj yeem sawv ntawm qhov hluav taws xob muaj zog dhau thiab hloov nws cov qauv rau tsim kev ntiav zoo li conductive protrusion (luv luv; saib daim duab). Yog li ntawd, lub capacitor sai sai tso tawm.
Lub luag haujlwm ntawm dielectric hauv lub capacitor yog dab tsi?
Dielectrics hauv capacitors ua haujlwm peb lub hom phiaj: kom khaws cov phaj coj los ntawm kev sib cuag, tso cai rau cov phaj me me sib cais thiab yog li muaj peev xwm ntau dua; txhawm rau ua kom muaj peev xwm ua tau zoo los ntawm kev txo cov hluav taws xob hluav taws xob, uas txhais tau tias koj tau txais tib yam nqi ntawm qhov qis dua; thiab.

Thaum cov ntaub ntawv dielectric muab tso rau hauv lub capacitor lub capacitance?
Thaum peb tso lub dielectric ntawm ob daim hlau ntawm lub phaj sib luag, lub tshuab hluav taws xob polarises nws. Tus nqi deg densities yog σ p thiab - σ p Thaum peb tso lub dielectric tag nrho ntawm ob daim hlau ntawm lub capacitor, ces nws yog dielectric tas li nce.
Los ntawm ntxig ib lub phaj ntawm cov khoom siv dielectric?
Los ntawm kev ntxig ib lub phaj ntawm cov khoom siv dielectric ntawm daim hlau ntawm cov phaj sib luag, lub zog tau nce tsib zaug . Yuav ua li cas thaum koj ntxig lub dielectric? Qhia dielectric rau hauv lub capacitor txo qis hluav taws xob, uas txo qhov voltage, uas ua rau kom muaj peev xwm.
Lub sijhawm beowulf lub sijhawm tus huab tais ntawm Danes yog?
Hrothgar yog Vaj Ntxwv ntawm Danes (Denmark) qub phooj ywg ntawm Beowulf txiv thiab txiv ntxawm. Hrothgar yog ib tug tub rog loj thiab ib tug txiv neej uas muaj hwj chim, tab sis tsis muaj peev xwm nrog Grendel . Leej twg yog tus huab tais ntawm Danes hauv Beowulf?
Lub sijhawm twg yog lub sijhawm them se ntawm ntsev qhia?
Txawm li cas los xij, kev siv cov ntsev ntsev hauv Is Nrias teb yog ib qho ntawm nws qhov siab tshaj plaws. Xyoo 1835, lub tuam txhab British East Is Nrias teb tau ua thawj zaug se ntawm ntsev hauv Is Nrias teb, lub tuam txhab British East Is Nrias teb raug coj los ntawm lub kaus mom xyoo 1858 vim yog cov nyiaj tau los ntau.
Puas yog sijhawm sijhawm lossis sijhawm sijhawm?
Raws lub npe qhov txawv ntawm sijhawm sijhawm thiab sijhawm sijhawm yog qhov sijhawm sijhawm yog lub sijhawm ua raws sijhawm thaum sijhawm sijhawm yog sijhawm sijhawm; qhov tseeb . Puas yog lub sijhawm sijhawm ib lo lus? adj. 1. Ua los yog tuaj txog raws li lub sijhawm teem tseg;
