Hauv electronics, ib LED Circuit los yog LED tsav tsheb yog ib qho hluav taws xob Circuit Court siv los ua lub zog tawm-emitting diode ( LED ). Qhov voltage poob ntawm ib qho LED yog kwv yees tas li ntau ntawm kev ua haujlwm tam sim no; Yog li ntawd, ib qho kev nce me me hauv kev siv hluav taws xob zoo heev ua rau qhov tam sim no.
Tom qab ntawd, LED tsav tsheb Circuit Court ua haujlwm li cas?
Txoj cai ntawm LED tsav tsheb LEDs tau dhau los ua ntau nyob rau lub sijhawm luv luv ntawm lub sijhawm, vim tias LED tsav Circuit tsis xav tau atransformer hauv lub hwj chim. Cov tsav tsheb tsim muaj AC capacitors uas txuas nrog hauv ib kab tom qab lwm qhov.
Tsis tas li ntawd, lub teeb LED ua haujlwm li cas? Lub teeb-emitting diodes ( LED ) yog cov khoom siv hluav taws xob (semiconductors) Raws li cov hluav taws xob hla los ntawm cov khoom siv hluav taws xob no, nws hloov mus rau qhov tsaus ntuj. Piv rau cov roj teeb thiab CFL qhov muag teev , LED teeb pom kev zoo dua ntawm kev hloov lub zog mus rau hauv lub teeb. Yog li ntawd, tsawg dua ntawm lub zog radiates los ntawm noob cua sov.
Raws li txoj cai, LED ua haujlwm yooj yim piav qhia li cas?
Lub teeb-emitting diode yog ob-lead semiconductor teeb pom kev zoo. Nws yog p -n kev sib tshuam diode uas tso tawm lub teeb thaum qhib. Thaum siv qhov hluav taws xob tsim nyog rau cov hlau lead, cov hluav taws xob muaj peev xwm sib sau ua ke nrog cov tshuab hluav taws xob nyob hauv cov cuab yeej, tso tawm lub zog hauv daim ntawv ntawm photons.
Puas yog LEDs xav tau cov resistors?
Ib txhia LEDs xws li hloov xim LEDs , nyem nyem LEDs thiab 5v LEDs yog tsim los khiav tawm a5V mov thiab yog li tsis txhob xav tau a resistor . Txhua tus qauv thiab ci LEDs yuav xav tau ib txoj cai tam sim no resistor . LED sawv rau Lub Teeb Emitting Diode thiab lub npe qhia, nws yog diode uas tso tawm lub teeb.

Koj puas tuaj yeem siv DC fuse hauv AC Circuit Court?
Lub fuse yuav tsum muaj tsawg kawg yog qhov ntsuas hluav taws xob ntawm lub Circuit Court nws tiv thaiv. Koj ib txwm tuaj yeem tso qhov ntsuas hluav taws xob ntau dua nyob rau hauv Circuit Court tab sis amperage myst zoo ib yam. DC fuse yuav tsis tiv thaiv zoo hauv AC Circuit. Vim tias qhov ntawd yuav yog qhov sib npaug fuse qhov ntsuas ntawm 20A rau tib qhov hluav taws xob
Tus dimmer hloov ua haujlwm li cas hauv Circuit Court?
Ib qho hloov tshiab niaj hnub dimmer 'chops up' sine wave. Nws cia li kaw lub teeb hluav taws xob hluav taws xob tawm txhua lub sijhawm tam sim no thim rov qab cov lus qhia - uas yog, thaum twg muaj qhov xoom hluav taws xob khiav los ntawm Circuit Court. Lub voj voog yog qhib rau feem ntau ntawm lub voj voog, yog li nws muab ntau lub zog ib ob rau lub teeb
Koj tuaj yeem tshawb xyuas ABS Circuit Court li cas?
Yuav Ua Li Cas Ntsuas ABS Sensor Siv Voltmeter? Nrhiav thiab tshem tawm lub connector. Saib rau lub tshuab txuas hluav taws xob los ntawm qee qhov ntsuas lub log nrawm uas nyob ze ntawm tus ncej hauv lub log feem ntau. Teem lub voltmeter. Ua xeem
Lub cav coolant kub qis Circuit Court txhais li cas?
Qhov yuam kev Code P0117 yog piav raws li Cav Coolant Temperature (ECT) Sensor Circuit Low Input. Lub ntsiab lus, PCM (lub zog tswj lub zog tswj, tseem hu ua ECM lossis lub cav tswj lub cav) txiav txim siab ECT lub zog tso tawm mus tsawg dua 0.14V lossis siab dua 284˚ F (140˚ C)
Camshaft txoj haujlwm sensor lub txhab nyiaj 1 Circuit tsis ua haujlwm txhais li cas?
Qhov yuam kev P0340 yooj yim txhais tau hais tias lub khoos phis tawj tau xa lub teeb liab mus rau lub camshaft txoj haujlwm sensor txawm li cas los nws tsis pom lub teeb liab raug uas tau rov qab los ntawm lub sensor. Txij li thaum lub Circuit Court yog kev txhawj xeeb, qhov teeb meem tuaj yeem yog ib qho ntawm cov khoom siv hluav taws xob xws li PCM, thaiv thiab ntsuas nws tus kheej
