Bikunze kugaragara ko abatangiye benshi barimo guterera kuri résistance mugihe basana uruziga, kandi rugasenywa rukanasudwa. Mubyukuri, yarasanwe cyane. Mugihe usobanukiwe ibyangiritse biranga kurwanywa, ntugomba kumara umwanya munini.

Kurwanya nikintu kinini mubikoresho byamashanyarazi, ariko ntabwo aricyo kintu gifite igipimo cyangiritse cyane. Gufungura umuzunguruko nubwoko busanzwe bwo kwangirika. Ntibisanzwe ko agaciro ko guhangana kaba nini, kandi agaciro ko guhangana kaba nto. Mubisanzwe harimo ibyuma birwanya karubone, ibyuma birwanya ibyuma, ibyuma bikomeretsa insinga hamwe n’ubwishingizi.

Ubwoko bubiri bwa mbere bwurwanya ni bwo bukoreshwa cyane. Kimwe mu biranga ibyangiritse ni uko igipimo cy’ibyangiritse cyo kurwanya bike (munsi ya 100Ω) no guhangana cyane (hejuru ya 100kΩ) ari hejuru, kandi agaciro kangana hagati (nka ohm amagana kugeza kuri kilohms icumi) Kwangirika gake cyane; Icya kabiri, iyo résistoriste nkeya yangiritse, akenshi irashya kandi ikirabura, ibyo bikaba byoroshye kuyibona, mugihe irwanya-résistance yangirika gake.

Kurwanya Wirewound muri rusange bikoreshwa mukugabanya umuvuduko mwinshi, kandi kurwanya ntabwo ari binini. Iyo insinga ya silindrike irwanya umuriro, bamwe bazahinduka umukara cyangwa hejuru igaturika cyangwa igacika, kandi bamwe ntibazagira ibimenyetso. Kurwanya sima ni ubwoko bwurugingo rukomeretsa insinga, rushobora kumeneka iyo rwatwitse, bitabaye ibyo ntihazagaragara ibimenyetso bigaragara. Iyo rezistor ya fuse yaka, igice cyuruhu kizaturika hejuru yubutaka bumwe, kandi bamwe ntibafite ibimenyetso, ariko ntibizigera bitwika cyangwa ngo bihinduke umukara. Ukurikije ibiranga haruguru, urashobora kwibanda mugusuzuma ibyangiritse hanyuma ukabona vuba ibyangiritse.

Dukurikije ibiranga byavuzwe haruguru, turashobora kubanza kureba niba abarwanya-buke buke ku kibaho cyumuzunguruko batwitse ibimenyetso byirabura, hanyuma dukurikije ibiranga ko benshi mubarwanya bafunguye cyangwa abarwanya bakaba banini kandi bakarwanya cyane. byangiritse byoroshye. Turashobora gukoresha multimeter kugirango dupime mu buryo butaziguye kurwanywa kumpande zombi zumurwanya-mwinshi kurubaho. Niba ibipimo byapimwe biruta ibyo kurwanywa kwizina, kurwanywa bigomba kwangirika (menya ko guhangana bihamye mbere yo kwerekanwa Mu gusoza, kubera ko hashobora kuba ibintu bifitanye isano na capacitifike mumuzunguruko, hariho uburyo bwo kwishyuza no gusohora), niba ibipimo byapimwe ni bito kurenza kurwanya nominal, muri rusange birengagizwa. Muri ubu buryo, buri rugamba ruri ku kibaho cy’umuzunguruko rwongeye gupimwa, kandi niyo igihumbi “cyicwa nabi”, ntazabura.
