Parallel-Plate Capacitor Thaum muaj qhov voltage V siv rau lub capacitor, nws khaws cov nqi Q, raws li qhia. … Ib yam li ntawd, qhov uas cov phiaj ze zog ua ke, qhov kev nyiam ntawm cov nqi sib txawv ntawm lawv ntau dua. Yog li ntawd, C yuav tsum ntau dua rau qhov me me d.
Koj puas yuav muab cov phiaj xwm ntawm lub phaj sib npaug ntawm lub capacitor ze dua ua ke?
Teb: Txhawm rau kom muaj peev xwm nce ntxiv, cov phiaj xwm ntawm cov phaj sib npaug yuav tsum yog tso ze ua ke. … Teb: Yog hais tias daim hlau muaj ntau qhov chaw lawv yuav tau txais cov nqi sib txawv vim tus nqi yog proportional rau capacitance thiab capacitance inversely proportional rau cheeb tsam.
Qhov twg feem ntau yog muab tso rau nruab nrab ntawm ob daim phiaj ntawm cov phaj sib npaug?
Tus qauv yooj yim tshaj plaws rau lub capacitor yog ib lub phaj sib luag, uas muaj ob lub phaj hlau nrog qhov sib txawv ntawm lawv: electrons muab tso rau hauv ib phaj(cov phaj tsis zoo), thaum sib npaug ntawm cov electrons raug tshem tawm ntawm lwm lub phaj (lub phaj zoo).
Yuav ua li cas rau qhov muaj peev xwm ntawm cov phaj sib npaug?
Kev piav qhia: Thaum qhov kev ncua deb ntawm daim phiaj txo qis qhov peev xwm sib txawv yuav qis dua, yog li lub peev xwm yuav nce ntxiv. Apropos nce qhov loj ntawm daim hlau, uas yuav ua rau kom muaj peev xwm nce ntxiv raws li Cheeb Tsam yog ncaj qha proportional rau lub capacitance.
Koj puas tuaj yeem tso lub phaj sib npaug ntawm cov kab hluav taws xob uas muaj ob daim phiaj ntawm 1 farad hauv koj lub almirah?
Koj puas tuaj yeem tso lub phaj sib npaug (muaj ob daim phiaj) ntawm 1 farad hauv koj lub almirah? Ans. No. Piv txwv tias ob daim hlau ntawm lub capacitor yog sib cais los ntawm qhov deb me me li 1 mm.
