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.

Puas yog cov dab dab dab dab dab dab dab dab dab dab dab dab?
Myth: Ib tug dab tshos tsis yog neeg ncaj ncees yog tiasnws haum yog. Fact: Tu siab, qhov no yog ib lo lus tsis tseeb uas tau raug perpetuated los ntawm aversive trainers. Txawm hais tias haum rau lub caj dab kom zoo khawb rau hauv cov tawv nqaij rhiab nyob ib ncig ntawm lub caj dab, uas ua rau muaj kev puas tsuaj loj rau cov thyroid, esophagus, thiab trachea.
Dab tsi yog kev xav ntawm autonomists dab tsi yog qhov kev xav ntawm kev zoo nkauj ntawm kev coj ncaj ncees?
Kev lig kev cai, muaj ob txoj haujlwm tawm tsam kev xav txog kev coj ua raws li kev cai lij choj ntawm kev ntsuas kev ncaj ncees ntawm kev kos duab: 'kev coj ncaj ncees kev ncaj ncees Ethics lossis kev coj ncaj ncees yog ib ceg ntawm kev xav uas "
Ntawm dab tsi yog qhov kev tiv thaiv ntawm tus neeg xyuas pib nyob ntawm?
Qhov kev tawm tsam ntawm tus neeg xyuas pib nyob ntawm thaj tsam ntawm tus neeg xyuas pib, qhov ntev ntawm tus neeg xyuas pib, thiab nws qhov kev tiv thaiv. Nws yog ib qho tseem ceeb kom nco ntsoov tias hluav taws xob conductivity thiab resistivity yog inversely proportional, txhais tau hais tias qhov ntau conductive ib yam dab tsi yog qhov tsawg resistive nws yog.
Dab tsi yog qhov ceev ntawm cov hlau raug tshem tawm los ntawm lub cuab yeej ntawm lub workpiece?
1. Kev nrawm . Kev txiav ceev (v) ntawm ib lub cuab yeej yog qhov ceev uas cov hlau raug tshem tawm los ntawm lub cuab yeej ntawm lub workpiece. Nyob rau hauv ib lub tshuab dhos, nws yog lub peripheral ceev ntawm kev ua hauj lwm yav dhau los cov cuab yeej txiav qhia nyob rau hauv meters ib feeb.
Qhov chaw twg yog qhov zoo dua yog dab tsi yog cov qauv siv lub locator?
ID thiab lub npe tus cwj pwm ua qhov tseem ceeb tshaj lwm qhov chaw yog tias koj lub vev xaib muaj tus ID thiab lub npe tshwj xeeb, ces nws ib txwm xav kom siv lawv hloov XPath vim lawv nrawm dua thiab ntau dua muaj txiaj ntsig. Thaum siv cov chaw nyob, xyuas kom meej tias koj lub chaw nrhiav cov ntsiab lus meej rau cov khoom xav tau.
