Lub peev xwm ntawm lub capacitor yog lub peev xwm ntawm lub capacitor los khaws cov nqi hluav taws xob ib chav tsev ntawm qhov hluav taws xob thoob plaws nws daim hlau ntawm lub capacitor. Capacitance pom los ntawm kev faib hluav taws xob nrog hluav taws xob los ntawm cov qauv C=Q/V.
Koj suav li cas capacitance?
Qhov kev sib npaug dav dav rau lub peev xwm ntawm lub phaj sib luag yog muab raws li: C=ε(A / d) qhov twg ε sawv cev rau qhov tsis txaus ntseeg ntawm cov khoom siv dielectric siv..
Tus qauv ntawm lub capacitor thiab capacitance yog dab tsi?
Cov kab zauv tswj hwm rau kev tsim capacitor yog: C=εA/d, Hauv qhov sib npaug no, C yog capacitance; ε yog permittivity, ib lo lus rau zoo npaum li cas cov khoom siv dielectric khw muag khoom hluav taws xob; A yog thaj tsam ntawm cov phaj sib luag; thiab d yog qhov kev ncua deb ntawm ob daim hlau conductive.
SI unit ntawm capacitor yog dab tsi?
Lub SI chav ntawm lub peev xwm yog tus farad(cim: F), muaj npe tom qab Askiv tus kws kho mob Michael Faraday. A 1 farad capacitor, thaum them nrog 1 coulomb ntawm hluav taws xob, muaj qhov sib txawv ntawm 1 volt ntawm nws daim hlau. Lub reciprocal ntawm capacitance hu ua elastance.
tus qauv tam sim no yog dab tsi?
Tus qauv tam sim no yog muab raws li I=V/R. SI unit ntawm tam sim no yog Ampere (Amp).
