Qhov txawv 1: txhais thiab muaj nuj nqi
DC tsis kam yog hais txog cov khoom uas cuam tshuam qhov kev nkag ntawm tam sim no hauv DC Circuit Court, ntsuas hauv ohms (Ω). Nws tuaj yeem siv los tswj qhov tam sim no hauv Circuit Court thiab ruaj khov ntawm kev ua haujlwm ntawm lub voj voog, thaum lub rwb thaiv tsev tiv thaiv yog hais txog cov khoom uas muab kev sib cais ntawm cov tam sim no hauv Circuit Court, ntsuas hauv ohms lossis megaohms (M Ω). Rwb thaiv tsev kuj yog siv los tiv thaiv tam sim no to thiab rwb thaiv tsev tsis ua hauj lwm, thiab tiv thaiv kev ruaj ntseg ntawm circuits thiab khoom siv.
Qhov txawv 2: Cov khoom siv thiab cov qauv
DC tsis kam yog feem ntau yog ua los ntawm cov khoom siv hlau, xws li tooj liab lossis hlau, uas hloov qhov kev tiv thaiv tus nqi los ntawm kev tswj qhov chaw hla ntu thiab qhov ntev ntawm tus neeg xyuas pib, thaum rwb thaiv tsev tiv thaiv yog ua los ntawm cov khoom tsis yog xim hlau, xws li iav fiber lossis yas. , uas muaj rwb thaiv tsev zoo heev los tiv thaiv tam sim no to thiab Circuit Court faults. Tsis tas li ntawd, rwb thaiv tsev kuj feem ntau yog txheej txheej los txhim kho nws lub peev xwm rwb thaiv tsev.
Qhov sib txawv peb: txoj cai ua haujlwm
DC tsis kam hloov cov khoom ntawm tus neeg xyuas pib nws tus kheej, ua rau tam sim no ntsib teeb meem tseem ceeb. Nws tsim kev tiv thaiv los ntawm kev cuam tshuam cov ntws ntawm electrons, tsim kom muaj tus nqi ruaj khov rau qhov tam sim no hauv Circuit Court. Rwb thaiv tsev kuj yog raws li kev rwb thaiv tsev kev ua tau zoo ntawm cov khoom, feem ntau yog los ntawm kev cuam tshuam cov conduction ntawm tam sim no nyob rau saum npoo los yog hauv cov khoom, yog li ua tiav tam sim no kev sib cais.
Qhov txawv plaub: Daim ntawv thov teb
DC tsis kam yog dav siv hauv hluav taws xob thiab hluav taws xob engineering. Nws feem ntau yog siv los kho qhov tam sim no thiab voltage hauv circuits, tiv thaiv cov khoom siv hluav taws xob los ntawm kev puas tsuaj ntau dhau tam sim no, thaum lub rwb thaiv tsev tiv thaiv feem ntau yog siv hauv cov tshuab hluav taws xob thiab cov khoom siv hluav taws xob siab los tiv thaiv cov cuab yeej thiab cov neeg ua haujlwm los ntawm kev puas tsuaj arc thiab to.
Qhov txawv 5: Kev ntsuas ntsuas
Kev ntsuas ntawm DC tsis kam yog qhov yooj yim thiab ncaj qha, feem ntau ntsuas los ntawm multimeter lossis ntsuas ntsuas, thaum ntsuas kev tiv thaiv hluav taws xob yuav tsum tau tshwj xeeb rwb thaiv tsev ntsuas ntsuas ntsuas. Kev ntsuas ntawm rwb thaiv tsev tiv thaiv feem ntau yog ua los ntawm high voltage, thiab kev ua haujlwm ntawm rwb thaiv tsev tiv thaiv yog ntsuas los ntawm kev siv high voltage.
Hauv cov ntsiab lus, txawm hais tias DC tsis kam thiab rwb thaiv tsev tiv thaiv yog cov khoom tiv thaiv hauv cov khoom siv hluav taws xob, lawv muaj qhov sib txawv tseem ceeb hauv cov ntsiab lus, cov ntaub ntawv, cov qauv kev ua haujlwm, daim ntawv thov, thiab cov qauv ntsuas. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau kev xaiv kom raug thiab siv cov khoom siv hluav taws xob kom ntseeg tau tias muaj kev nyab xeeb thiab ruaj khov ntawm circuits thiab khoom siv.
