Nws yog feem ntau pom tias ntau cov pib tshiab yog pov rau kev tiv thaiv thaum kho cov Circuit Court, thiab nws yog dismantled thiab welded. Qhov tseeb, nws tau kho ntau. Tsuav koj nkag siab qhov kev puas tsuaj ntawm cov kev tiv thaiv, koj tsis tas yuav siv sijhawm ntau.

Kev tawm tsam yog cov feem ntau cov khoom siv hauv cov khoom siv hluav taws xob, tab sis nws tsis yog cov khoom tivthaiv nrog kev puas tsuaj ntau tshaj plaws. Qhib Circuit Court yog hom kev puas tsuaj ntau tshaj plaws. Nws yog qhov tsawg uas tus nqi tiv taus loj dua li loj dua, thiab tus nqi tiv dhau los ua me dua. Cov uas nquag muaj xws li carbon film resistors, hlau yeeb yaj kiab tsim, hlau cov txuj ci tsim thiab tsim kev tuav pov hwm.

Thawj ob hom resistors yog qhov dav tshaj plaws. Ib qho ntawm cov yam ntxwv ntawm lawv cov kev puas tsuaj yog tias qhov kev puas tsuaj yog tias qhov kev puas tsuaj ntawm cov nqi qis (xws li ntau pua ntawm ohms rau tens ntawm kiloohms) me ntsis kev puas tsuaj; Thib ob, thaum cov khoom siv qis tiv thaiv tau puas, lawv feem ntau hlawv thiab dub, uas yog qhov yooj yim mus nrhiav, thaum lub siab tiv taus cov tsis tshua muaj kev puas ntsoog.

Wirewound cov tsis taus feem ntau yog siv rau cov kev txwv tam sim no, thiab cov kev tawm tsam tsis loj. Thaum cylindrical cov hlau hluav taws xob tiv thaiv hlawv tawm, qee tus yuav tig xim dub lossis cov npoo yuav tawg lossis tawg, thiab qee tus yuav tsis muaj kab. Maas defitors yog ib hom xov hlau uas tsis kam, uas yuav tawg thaum hlawv tawm, txwv tsis muaj qhov yuav tsis pom kev. Thaum lub fuse resistor hlawv tawm, ib daim tawv nqaij yuav tawg tau ntawm qee qhov chaw, thiab qee leej tsis tau hlawv lossis tig dub. Raws li cov yam ntxwv saum toj no, koj tuaj yeem tsom rau kev kuaj xyuas qhov tsis kam thiab nrhiav tau cov kev puas tsuaj tiv thaiv.

Raws li cov yam ntxwv teev saum toj no, peb tuaj yeem thawj zaug saib seb qhov kev tiv thaiv kab Circuit Course uas feem ntau ua rau cov neeg tawm tsam thaj tsam uas feem ntau ua rau muaj kev puas tsuaj loj thiab kev ua haujlwm hnyav tau yooj yim. Peb tuaj yeem siv cov puv ntom ncaj qha ntsuas qhov tsis kam ntawm ob qho kawg ntawm kev tiv thaiv kev tiv thaiv zoo. Yog tias ntsuas kev tawm tsam ntau dua li cov nominal tsis kam (nco ntsoov tias kev tawm tsam yog me dua li ntawm nominal tsis kam, nws feem ntau tsis quav ntsej. Nyob rau hauv txoj kev no, txhua qhov kev tawm tsam ntawm Circuit Court Board yog ntsuas dua, thiab txawm tias ib txhiab yog "tsis ncaj ncees lawm tua", ib tus yuav tsis ploj.
