Thaum lub dielectric muab tso rau tag nrho nruab nrab ob tug daim hlau ntawm capacitor ces yog dielectric tas li nce los ntawm nws tus nqi nqus tsev vacuum. Yog li, thiab,  yog qhov kev tso cai ntawm cov khoom.

Xav txog qhov no, yuav ua li cas thaum lub dielectric tso rau hauv lub capacitor?

Ntxiv ib dielectric tso cai rau capacitor khaws cov nqi them ntau dua rau qhov muaj peev xwm sib txawv. Thaum a dielectric yog muab tso rau hauv tus nqi capacitor , cov dielectric yog polarized los ntawm teb. Electric teb los ntawm dielectric yuav ib feem tshem tawm hluav taws xob teb los ntawm tus nqi ntawm lub capacitor daim hlau.

Tom qab ntawd, lo lus nug yog, lub luag haujlwm ntawm cov khoom siv nruab nrab yog dab tsi yog tias nws muab tso rau ntawm daim phiaj ntawm lub capacitor? Cov khoom nruab nrab yog lub dielectric muab tso rau nruab nrab ob hlau daim hlau ntawm lub capacitor . Ntau hom dielectric nruab nrab yog siv rau ntau hom capacitor . Dielectric los yog insulating nruab nrab yog siv rau lub zog hauv nws. Dielectric los yog insulating nruab nrab yog siv rau lub zog hauv nws.

Tsis tas li ntawd, puas muaj cov khoom siv uas thaum muab tso rau ntawm daim hlau ntawm lub capacitor txo nws cov peev xwm?

Dielectrics. nruj me ntsis hais lus, cov lus qhia (108) rau lub capacitance ntawm ib lub phaj parallel capacitor tsuas yog siv tau yog tias cheeb tsam nruab nrab ntawm daim phiaj yog lub tshuab nqus tsev. Dielectric cov ntaub ntawv muaj cov nyhuv ntawm txo cov chaw hluav taws xob thiab qhov sib txawv muaj peev xwm tsim los ntawm cov nqi hluav taws xob.

Thaum twg cov khoom siv dielectric raug qhia?

Taw qhia dielectric nruab nrab ntawm cov phaj capacitor (nyob rau hauv qhov chaw ntawm huab cua) yuav ua rau kom tus nqi capacitor los ntawm ib qho tseem ceeb ntawm dielectric tas li. Yog hais tias nws yog ib qho kev rho tawm capacitor, tus nqi tseem zoo ib yam, thiab qhov hluav taws xob poob qis hauv qhov sib piv rau dielectric tas li.
