Yog li ntawd, raws li thaj tsam ntawm daim phiaj nce, kev muaj peev xwm nce ntxiv. Capacitance yog ncaj qha proportional rau lub electrostatic force teb ntawm daim hlau. Daim teb no muaj zog dua thaum cov phiaj xwm nyob ze ua ke. Yog li ntawd, raws li qhov kev ncua deb ntawm daim hlau txo, capacitance nce.
Koj tuaj yeem nce lub peev xwm ntawm lub capacitor li cas?
Yog tias koj xav ua kom muaj peev xwm ntawm Parallele Plate Capacitor ces nce qhov chaw saum npoo, txo qhov sib cais ntawm phaj thiab siv cov khoom siv dielectric nyob nruab nrab ntawm cov phaj uas muaj siab dua Lub zog dielectric zog.
Dab tsi yog yam cuam tshuam rau lub peev xwm?
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 me me qhov sib txawv, qhov loj dua qhov capacitance.
Qhov twg ntawm cov khoom hauv qab no Tsis tuaj yeem ntsuas los ntawm cov khoom siv hluav taws xob?
Capacitive transducers tsis tuaj yeem siv ua lim ntsuas. Nqe lus piav qhia: Txoj kev ntsuas yuav tsum tau siv rau cov kab hlau sib txuas ntawm lub capacitor thiab tag nrho cov kev hloov pauv yuav yog proportional to strain.
Yuav ua li cas hauv qab no yog qhov tseeb rau kev hloov pauv dej noo Mcq?
d yog qhov kev ncua deb ntawm daim phiaj. Dab tsi ntawm cov hauv qab no yog qhov tseeb rau kev hloov pauv dej noo? Kev daws: Dielectric tas li ntawm cov dej ntshiab yog 80, uas yog ntau dua li lwm cov ntaub ntawv; Cov yam ntxwv no pab ntsuas cov dej noo.
