Nws muaj peb yam uas cuam tshuam rau lub peev xwm: qhov loj ntawm cov conductors, qhov loj ntawm qhov sib txawv ntawm lawv, thiab cov khoom nruab nrab ntawm lawv (dielectric). Qhov loj dua cov conductors, lub capacitance loj dua. Qhov sib txawv me me, qhov loj dua qhov capacitance.
Ntawm yam dab tsi ua rau lub peev xwm ntawm lub capacitor nyob ntawm Chav 12?
Nws nyob ntawm geometry ntawm daim hlau, qhov deb ntawm lawv thiab qhov xwm txheej ntawm dielectric nruab nrab spearting cov phiaj.
capacitor txhais li cas capacitance ntawm lub capacitor ntawm dab tsi yog nws nyob ntawm seb?
Lub peev xwm ntawm lub capacitor, nyob ntawm cov hauv qab no: i) geometry ntawm daim hlau, ii) nrug ntawm cov phaj capacitor, thiab. iii) nature ntawm dielectric nruab nrab cais cov phiaj.
Ntawm qhov capacitance ntawm capacitor tsis nyob ntawm?
Ntawm no, A yog thaj tsam ntawm daim phiaj ntawm lub capacitor thiab d yog qhov kev ncua deb ntawm daim hlau. Yog li, peb tuaj yeem pom tseeb tias qhov capacitance ntawm lub capacitor yog nyob ntawm qhov loj thiab cov duab ntawm daim hlau thiab kev sib cais ntawm daim hlau; nws tsis yog nyob ntawm tus nqi ntawm daim phiaj.
chav tsev ntawm lub peev xwm yog dab tsi thiab nyob ntawm dab tsi nws nyob ntawm?
chav tsev ntawm lub peev xwm yog farad. Thiab nyob rau hauv lwm yam lus peb tuaj yeem txhais lub peev xwm raws li qhov peev xwm ntawm lub capacitor los khaws nqi. Qhov ntawd txhais tau hais tias qhov ntau tus nqi ntawm capacitance ntau dua nws tuaj yeem ua taukhw.
