Siv ib lub multimeter los xyuas kom meej tias tsis muaj luv luv Circuit Court nyob rau hauv nruab nrab hlau, uas yuav mus txawv tebchaws thaum lub hloov mus kaw. Lub teeb yog LED.
Qhov teeb meem yuav tsum yog nrog lub teeb, muaj ob peb yam uas tuaj yeem ua rau nws mus.
LDE teeb feem ntau yog tsim los ntawm kev hloov tsav tsheb fais fab thiab LED teeb hlaws thiab teeb vaj huam sib luag.
Thawj qhov xwm txheej yog tias cov khoom siv hluav taws xob hauv lub tshuab hluav taws xob hloov hluav taws xob raug puas tsuaj vim muaj teeb meem zoo. Yog tias qhov hloov pauv tsav lub zog hluav taws xob luv luv, lub zog hluav taws xob yuav tawm mus. Koj tuaj yeem siv multimeter los ntsuas seb puas muaj qhov ua haujlwm zoo li qub thiab tam sim no los txiav txim. DC kev khiav hauj lwm voltage thiab tam sim no ntawm txhua lub teeb LED sib txawv, thiab lawv feem ntau txuas nrog hauv series thiab sib npaug los tsim lub teeb vaj huam sib luag.
Qhov thib ob qhov teeb meem yog tias muaj ib qho luv luv Circuit Court board ntawm lub teeb vaj huam sib luag, ua rau lub tshuab hluav taws xob hloov hluav taws xob raug puas tsuaj thiab cov khoom siv hluav taws xob mus ncig.
Txawm hais tias nws yog lub teeb LED siv nyob rau hauv lub Hoobkas lossis hauv tsev, thaum nws ntsib kev mus txawv tebchaws, feem ntau yuav tsum tau hloov lub teeb qub nrog tib lub teeb tshiab. Yog tias qhov kev mus los yog tshwm sim los ntawm teeb meem nrog lub teeb, qhov tshwm sim tripping yuav raug tshem tawm. Qhov no yog ib txoj kev ceev los daws qhov teeb meem.
Tau kawg, yog tias qhov kev khiav hauj lwm tam sim no ntawm qhov hloov pauv huab cua tsawg dua qhov kev khiav hauj lwm tam sim no ntawm LED teeb, nws kuj yuav ua rau tsis muaj zog. Rau cov teeb pom kev zoo uas twb tau ua haujlwm zoo li ib qho ntawm cov lus nug no, nws yog dhau ntawm qhov kev sib tham.
Puas yog "lub rooj vag" koj siv lub tshuab hluav taws xob xau? Los yog ib qho hluav taws xob hluav taws xob zoo tib yam uas tsis muaj qhov xau tripping? Qhov ntsuas tam sim no yog dab tsi? Koj coj tau pes tsawg lub teeb LED?
Yog hais tias nws yog ib tug to Circuit Court breaker thiab cov nyob thiab nruab nrab nyob rau hauv tsis muaj luv luv-circuited, ces tej zaum yuav hais tias cov nyob los yog nruab nrab nyob rau hauv cov xov hlau yog to, los yog tej zaum nws yuav yog hais tias tus tswj Circuit Court ntawm ib co teeb los yog lub teeb nws tus kheej yog to. .
Puas yog qhov teeb meem no tsis muaj nyob rau yav dhau los thiab tsuas yog tshwm sim tam sim no? Los yog qhov kev xeem xa hluav taws xob tsis tuaj yeem kaw lub rooj vag tom qab txoj kab tau teeb tsa? Puas tau muaj kev kho dua tshiab tsis ntev los no?
Kuv ib zaug tau ntsib ib qho teeb meem uas ib tug kws ntoo tau tshwm sim los tsav cov ntsia hlau mus rau cov xov hlau nyob ntawm lub zog hluav taws xob vim kev kho dua tshiab. Vim tias kev tsim hluav taws xob tau ua tiav tib lub sijhawm raws li kev tsim kho ntawm cov ntoo, tom qab kuv tso cov xov hlau, cov kws ntoo ua haujlwm kho kom zoo nkauj, thiab cov teeb meem saum toj no tshwm sim. Tom qab tag nrho cov kev tsim hluav taws xob tau ua tiav, qhov kev ntsuas hluav taws xob tau ua tiav. Thaum lub qhov hluav taws xob hluav taws xob hluav taws xob tau qhib, lub suab "pop" tau hnov txog lwm qhov, thiab cov hluav taws xob hluav taws xob tau ploj mus.
"Raued". Kuv xav rau kuv tus kheej, tej zaum cov xov hlau nyob thiab nruab nrab yog luv luv. Siv ib lub multimeter thiab xyuas tias tsis muaj luv luv ntawm cov xov hlau nyob thiab nruab nrab. Xav rov qab ua tib zoo, kuv ua txhua qhov sib koom ua ke zoo heev, puas yog? Tsis yog luv luv?
Sim dua thiab nws tseem tripped. Thaum nws kaw dua, nws yuav tsis dhia, tab sis lub teeb tom qab ib qho ntawm ib qho yuav tsis teeb thiab lub qhov (socket) yuav tsis muaj hwj chim. Nws yog kwv yees tias muaj qhov xau ze ntawm node. Kev tshuaj xyuas pom tau hais tias cov xov hlau nyob ntawd tau cuam tshuam tag nrho vim yog ob peb lub zog sib law liag, yog li tsis muaj lub zog hauv cov kab txuas ntxiv ntawm no.
Cov saum toj no yog me ntsis ntawm kuv kev ua haujlwm.
Hauv kev teb rau cov lus nug uas tus neeg nug nug, peb yuav tsum daws qhov teeb meem tripping li cas? Nws raug nquahu kom kaw tag nrho lub teeb hloov ua ntej (feem ntau qhov hloov pauv tswj cov hlau nyob), thiab tom qab ntawd sim kaw lawv. Yog tias nws tseem mus ncig, nws txhais tau tias ob yam ua ntej. Ua ntej: qhov txhaum taw tes tsis yog ntawm txhua ceg teeb. Thib ob: Qhov no yog qhov ntsuas tsis muaj load thiab tsis muaj dab tsi cuam tshuam nrog qhov ntsuas tam sim no ntawm qhov hloov. Tsom ntsoov rau kev tshuaj xyuas thaj chaw ntawm txoj kab uas muaj kev tsim kho tsis ntev los no.
Yog tias koj tua tag nrho lub teeb hloov thiab muab lub zog, cov keyboards yuav tsis tawm mus. Koj tuaj yeem maj mam qhib cov keyboards ib qho los ntawm ib qho. Yog hais tias tus hloov mus txawv tebchaws thaum koj qhib ib lub teeb, ces qhov teeb meem nyob rau hauv lub tswj Circuit Court ntawm lub teeb los yog lub teeb. nws tus kheej. Thaum qhov dav dav ntawm qhov chaw txhaum raug txiav txim siab, kev kho yuav yooj yim dua.
Txoj kev daws teeb meem yog txoj kev siv ntau tshaj plaws los kho hom kev ua txhaum ntawm Circuit Court, uas tuaj yeem txiav txim siab sai sai ntawm qhov txhaum thiab txo lub sijhawm kho.
