Nws yog feem ntau pom tias muaj ntau tus neeg pib tshiab tossing ntawm qhov kev tawm tsam thaum kho lub voj voog, thiab nws yog dismantled thiab welded.Qhov tseeb, muaj ntau yam kev kho.Tsuav koj nkag siab txog cov yam ntxwv ntawm kev puas tsuaj, koj tsis tas yuav siv sijhawm ntau.

Resistor yog cov khoom siv ntau tshaj plaws hauv cov khoom siv hluav taws xob, tab sis nws tsis yog cov khoom uas muaj kev puas tsuaj ntau tshaj plaws.Qhib Circuit Court yog hom kev puas tsuaj feem ntau.Nws tsis tshua muaj qhov tsis kam ua kom loj dua, thiab nws tsis tshua muaj qhov tsis kam ua kom me me.Feem ntau muaj xws li carbon film resistors, hlau zaj duab xis resistors, hlau qhov txhab resistors thiab pov hwm resistors.

Thawj ob hom resistors yog siv dav tshaj plaws.Ib qho ntawm cov yam ntxwv ntawm lawv qhov kev puas tsuaj yog qhov kev puas tsuaj loj ntawm kev ua haujlwm qis (qis dua 100Ω) thiab siab tsis kam (siab tshaj 100kΩ), thiab qhov nruab nrab tsis kam (xws li ntau pua ohms mus rau kaum ntawm kiloohms) Kev puas tsuaj tsawg heev;Thib ob, thaum cov resistors tsis tshua muaj kev puas tsuaj, lawv feem ntau hlawv thiab blackened, uas yog ib qho yooj yim mus nrhiav tau, thaum high-resistance resistors tsis tshua muaj kev puas tsuaj.

Wirewound resistors feem ntau yog siv rau siab tam sim no limiting, thiab cov kuj tsis loj.Thaum cylindrical hlau qhov txhab resistors raug hlawv, qee qhov yuav tig dub los yog saum npoo yuav tawg lossis tawg, thiab qee qhov yuav tsis muaj kab.Cement resistors yog ib hom hlau qhov txhab tiv thaiv, uas tuaj yeem tawg thaum hlawv tawm, txwv tsis pub yuav tsis muaj qhov pom.Thaum lub fuse resistor kub hnyiab tawm, ib daim tawv nqaij yuav tawg rau ntawm qhov chaw, thiab qee qhov tsis muaj kab, tab sis nws yuav tsis hlawv lossis dub.Raws li cov yam ntxwv saum toj no, koj tuaj yeem tsom mus rau kev kuaj xyuas qhov tsis kam thiab sai sai nrhiav cov kev puas tsuaj.

Raws li cov yam ntxwv uas tau teev tseg saum toj no, peb tuaj yeem soj ntsuam xyuas seb puas muaj qhov tsis kam tiv thaiv qis ntawm lub rooj tsav xwm hauv Circuit Court muaj ib qho kev kub hnyiab dub, thiab tom qab ntawd raws li cov yam ntxwv uas feem ntau ntawm cov resistors qhib los yog qhov tsis kam yuav loj dua thaum cov resistors yog. puas ntsoog, thiab lub siab-resistors yog yooj yim puas.Peb tuaj yeem siv multimeter ncaj qha ntsuas qhov tsis kam ntawm ob qho kawg ntawm qhov siab-resistor ntawm lub rooj tsav xwm Circuit Court.Yog hais tias qhov ntsuas tsis kam yog siab dua qhov nominal tsis kam, qhov kev tiv thaiv yuav tsum raug puas (nco ntsoov tias qhov kev tiv thaiv yog qhov ruaj khov tom qab cov zaub ruaj khov. Thaum xaus, vim tias tej zaum yuav muaj cov khoom sib luag hauv lub voj voog, muaj cov txheej txheem them nqi thiab tawm. ), Yog hais tias qhov ntsuas tsis kam yog me dua qhov nominal kuj, nws feem ntau tsis quav ntsej.Nyob rau hauv txoj kev no, txhua qhov kev tawm tsam ntawm lub rooj tsav xwm hauv Circuit Court yog ntsuas ib zaug, txawm tias ib txhiab yog "tua tsis raug", ib tus yuav tsis nco.
