Kuv yuav ua li cas yog tias lub capacitor tawg? Ntau tus neeg yuav muaj lo lus nug no. Lub capacitor ntawm kuv lub rooj tsavxwm tau tawg, tab sis kuv tsis paub tias nws lub peev xwm yog dab tsi. Kuv yuav ua li cas yog tias kuv hloov nws mus rau qhov loj dua?
Txoj hauv kev zoo tshaj los daws qhov teeb meem yog hloov lub capacitor nrog tib lub peev xwm hauv smt Hoobkas. Vim tias muaj ob peb lub capacitor, ntau ntawm lawv tsis cim nrog lawv lub peev xwm. Feem ntau, tag nrho disk yog cim nrog nws. Yuav ua li cas koj pom lub capacitance ntawm hluav taws xob thaj? Nyob rau hauv tus txheej txheem ntawm patch ua, nws yuav tsum tau kuaj nrog ib tug tester. Yog tias nws yog tib lub Hoobkas logo, lub peev xwm ntawm cov xim tsaus yuav loj dua li cov xim ntawm lub teeb, thiab xim av grey yog ntau dua lub teeb liab thiab grey. Txoj kev zoo tshaj plaws yog ntsuas nrog lub ntsuas capacitance.
Txoj kev ntsuas Capacitance:
Capacitors nyob rau hauv smt nti ua cov nroj tsuag yog ceramic capacitors, uas yuav tsum tau ua nyob rau hauv high kub, yog li tsis muaj nqi cim rau lawv. Capacitors feem ntau muab faib ua peb qhov xwm txheej: to thiab tawg lossis tsis muaj peev xwm. Yog tias nws raug kuaj pom, siv multimeter los kuaj xyuas qhov tsis kam thiab kho nws mus rau 10K-20K raws li tus qauv ntsuas, tshwj xeeb tshaj yog cov smt nti capacitance. Tus cwj mem taub ntawm lub 'meter' yuav tsum tau siv yog ntawm ob sab ntawm nws. Yog tias nws tus nqi nce, nws txhais tau tias nws yog qhov zoo, tab sis tus nqi capacitance yog 0, uas txhais tau tias nws tsis muaj peev xwm lossis tawg.
