Lub voj voog luv luv txhais tau hais tias lub voj voog lossis ib feem ntawm lub voj voog luv luv. Piv txwv li, cov khoom thauj thiab cov khoom siv hluav taws xob txuas nrog cov xov hlau, uas yog hu ua luv luv Circuit Court. Tam sim no muab los ntawm lub hwj chim mov thaum lub sij hawm luv luv Circuit Court yuav ntau dua li qhov tam sim no muab los ntawm txoj kev. Feem ntau, luv luv Circuit Court tsis raug tso cai. Yog tias qhov luv luv Circuit Court yog qhov hnyav, cov khoom siv hluav taws xob lossis cov khoom siv yuav raug hlawv.
Nyob rau hauv lub hwj chim system, lub thiaj li hu ua" luv luv Circuit Court" hais txog kev sib txuas ntawm theem lossis nruab nrab ntawm theem thiab hauv av (lossis nruab nrab) sab nraud ntawm kev ua haujlwm ntawm lub zog ntawm lub cev. Cov ntaub ntawv tseem ceeb ntawm luv Circuit Court nyob rau hauv peb-theem system yog: peb-theem luv luv-circuit, ob-theem luv luv-circuit, ib-theem grounding luv-circuit, thiab ob-theem grounding luv-circuit.
Tam sim no loj heev ntws thaum muaj kev sib txuas tsis zoo (ie luv luv Circuit Court) tshwm sim ntawm theem lossis nruab nrab ntawm theem thiab hauv av (lossis nruab nrab). Tus nqi tam sim no ntau dua li qhov ntsuas tam sim no thiab nyob ntawm qhov hluav taws xob nyob deb ntawm qhov luv-circuit point thiab cov khoom siv hluav taws xob.
Ib qho luv luv Circuit Court yog qhov tsis tshua muaj hluav taws xob luv luv ntawm cov khoom siv hluav taws xob sib txawv, uas yog sib npaug rau lub voj kaw uas txuas ncaj qha los ntawm cov xaim tsis dhau lub load. (Feem ntau qhov no yog qhov loj heev thiab tsis ua haujlwm hauv Circuit Court yuav tsum zam kom ntau li ntau tau, uas yuav ua rau hluav taws kub hnyiab thiab ua rau hluav taws kub vim yog qhov tam sim no ntau dhau).
Luv luv Circuit Court ntawm lub hwj chim mov txhais tau hais tias nyob rau hauv Circuit Court, tam sim no tsis ntws los ntawm cov khoom siv hluav taws xob, tab sis ncaj qha mus rau lub zoo thiab tsis zoo ncej ntawm lub hwj chim mov. Raws li Ohm' txoj cai lij choj I=U / R, vim tias qhov kev tiv thaiv ntawm cov xaim me me, qhov tam sim no ntawm Circuit Court yuav loj heev thaum lub hwj huam mov luv luv.
Xws li ib tug loj tam sim no yuav tsis muaj peev xwm tiv taus lub roj teeb lossis lwm yam khoom siv hluav taws xob, thiab nws yuav ua rau lub zog puas tsuaj. Dab tsi yog qhov hnyav dua yog vim tias tam sim no loj heev, qhov kub ntawm cov hlau yuav nce, uas yuav ua rau muaj hluav taws kub heev.
