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).

Thaum cov ntaub ntawv dielectric muab tso rau hauv lub capacitor lub capacitance?
Thaum peb tso lub dielectric ntawm ob daim hlau ntawm lub phaj sib luag, lub tshuab hluav taws xob polarises nws. Tus nqi deg densities yog σ p thiab - σ p Thaum peb tso lub dielectric tag nrho ntawm ob daim hlau ntawm lub capacitor, ces nws yog dielectric tas li nce.
Yuav ua li cas xam mtbf ntawm lub kaw lus raws li cov khoom sib txuas?
Lambda System=Lambda tivthaiv 1 + Lambda tivthaiv 2 + Lambda tivthaiv n. MTBF System=1 / Lambda System . Koj suav MTBF li cas? Xaiv MTBF, faib tag nrho cov sijhawm ua haujlwm hauv ib lub sijhawm los ntawm tus lej ntawm kev ua tsis tiav uas tshwm sim nyob rau lub sijhawm ntawd.
Lub sijhawm dielectric tawg ntawm lub capacitor?
Thaum siv lub dielectric, khoom nruab nrab ntawm cov paib sib npaug ntawm lub capacitor yuav polarize… Thaum kawg txhua yam khoom muaj "dielectric breakdown point," uas qhov sib txawv yuav dhau los. siab dhau rau nws insulate, thiab nws ionizes thiab tso cai rau txoj kev tam sim no .
Puas yuav lub tsev qiv nyiaj yuav lub tshuab xam zauv?
A lub laij lej yog ib yam khoom me me uas muaj nqis tiag tiag nyiaj tsim nyog uas ua rau nws zoo tagnrho rau lub khw muag khoom . Lub tsev qiv nyiaj yuav them tshaj li cas? Cov hauv qab no yog cov khoom lag luam uas yuav luag ib txwm yuav:
Yuav ua li cas xam cov nqi depreciation recapture ntawm cov khoom xauj tsev?
Yuav Ua Li Cas Xa Khoom Depreciation Rov Qab Ua Haujlwm Tag nrho lees paub nce=$ 176, 360. Depreciation expense=$36, 360 x 24% tax rate=$8,726 tax based on income bracket. Txuag nce=$ 176, 360 - $ 36, 360 tus nqi depreciation=$ 140, 000 x 15%=$ 21, 000 se raws li peev nyiaj tau los.
