Ib qho khoom siv dielectric yog siv los cais cov paib hluav taws xob ntawm lub capacitor. Cov khoom siv insulating no tseem ceeb txiav txim siab txog cov khoom ntawm cov khoom. Lub dielectric qhov tsis tu ncua ntawm cov khoom txiav txim siab npaum li cas ntawm lub zog uas lub capacitor tuaj yeem khaws cia thaum siv hluav taws xob.

Vim li cas dielectrics siv hauv cov khoom siv hluav taws xob?

Dielectrics hauv capacitors pab peb lub hom phiaj: kom cov hlau ua kom tsis txhob muaj 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 hais tias koj tau txais tib yam nqi ntawm qhov qis dua; thiab.

Vim li cas cov khoom siv dielectric hauv lub capacitor yuav tsum yog ib qho insulator?

cov khoom siv hluav taws xob zoo li ua kom muaj cua sov ntau dua li cua, thiab yog li los ntawm kev siv cov khoom zoo li no cov phaj (hauv ib lub phaj sib npaug) tuaj yeem muab tso rau ze rau ua ke uas yuav ua tau ntau dua. capacitance. Capacitors nrog cua nyob nruab nrab ntawm lawv muaj. ε0 yog qhov tsis tu ncua (nqus permittivity).

Dab tsi yog siv cov khoom siv dielectric?

Dielectrics yog siv los ua a capacitor rau khaws cia lub zog. Cov khoom siv dielectric nyob rau hauv lub transformer yog siv los ua ib qho insulator thiab ua kom txias. Txhawm rau txhim kho kev ua tau zoo ntawm cov khoom siv hluav taws xob semiconductor, cov khoom siv siab permittivity dielectric yog siv.

Puas yog ntawv yog cov khoom siv dielectric?

Ntau dua yog siv los ua kev txhawb nqa kev sau ntawv thiab hauv kev ntim khoom, ntawv kuj tau siv hauv hluav taws xob ua hluav taws xob ua hluav taws xob hauv hluav taws xob hloov hluav taws xob thiab kev siv hluav taws xob siab. … Tseeb tiag, daim ntawv muaj ib qho dielectric tsis tu ncua (nruab nrab ntawm 1 txog 2.5) nrog rau cov cellulose ntshiab (6 txog 8.1) [7].
