Kuvame ukubonakala ukuthi abaqalayo abaningi baphonsa ukumelana lapho belungisa umjikelezo, futhi idilizwa futhi ihlanganiswe.Eqinisweni, kuningi okulungiswayo.Inqobo nje uma uqonda izici zomonakalo zokumelana, akudingekile ukuba uchithe isikhathi esiningi.
I-Resistor iyisakhi esiningi kakhulu ezintweni zikagesi, kodwa akuyona ingxenye enezinga eliphezulu lomonakalo.Isekhethi evulekile iwuhlobo oluvame kakhulu lomonakalo wokumelana.Akuvamile ukuthi ukumelana kube kukhulu, futhi akuvamile ukuthi ukumelana kube kuncane.Ezivamile zihlanganisa izinqamuleli zefilimu ye-carbon, izihlungi zefilimu yensimbi, izihlungi zenxeba lezintambo kanye nezinqamuli zomshuwalense.
Izinhlobo ezimbili zokuqala ze-resistors yizona ezisetshenziswa kakhulu.Esinye sezici zomonakalo wabo izinga eliphezulu lokulimala kokumelana okuphansi (ngezansi kwe-100Ω) nokumelana okuphezulu (ngaphezu kwe-100kΩ), nokumelana okuphakathi (njengamakhulu ama-ohms kuya kumashumi ama-kiloohms) Umonakalo omncane kakhulu;okwesibili, lapho ama-resistant-resistant-resistant alimala, avame ukushiswa futhi abe mnyama, okutholakala kalula, kuyilapho ama-resistant-resistant-resistant angavamile ukulimala.
Ama-Resistors e-Wirewound ngokuvamile asetshenziselwa umkhawulo ophezulu wamanje, futhi ukumelana akukukhulu.Uma izinto ezivimbela izilonda zezintambo eziyisilinda zishiswa, ezinye zizoba mnyama noma ingaphezulu liqhume noma liqhekeke, kanti ezinye ngeke zibe nomkhondo.Izithako zikasimende ziwuhlobo lwezinqamuli zenxeba zocingo, ezingase ziphuke lapho zishisiwe, ngaphandle kwalokho ngeke kube khona imikhondo ebonakalayo.Lapho i-fuse resistor isha, ucezu lwesikhumba luzoqhuma phezulu, kanti ezinye azinawo umkhondo, kodwa ngeke zishiswe noma zibe mnyama.Ngokusho kwezici ezingenhla, ungagxila ekuhloleni ukumelana futhi uthole ngokushesha ukumelana okonakele.
Ngokwezici ezibalwe ngenhla, singaqale sibheke ukuthi ngabe izinto eziphikisayo ezimelana kancane ebhodini lesifunda zinemikhondo yokushiswa okumnyama, bese ngokusho kwezici ukuthi iningi lama-resistors avulekile noma ukumelana kuba kukhudlwana lapho ama-resistors ekhona. ezilimele, futhi resistors high-ukumelana nokulimala kalula.Singasebenzisa i-multimeter ukuze silinganise ngokuqondile ukumelana kuzo zombili iziphetho ze-resistor ephezulu ebhodini lesifunda.Uma ukumelana okulinganiselwe kukhulu kunokumelana okulinganiselwe, ukumelana kufanele konakaliswe (qaphela ukuthi ukumelana kuzinzile ngemva kokuba isibonisi sizinzile. Ekugcineni, ngenxa yokuthi kungase kube nezakhi ze-capacitive ezihambisanayo kumjikelezo, kunenqubo yokushaja nokukhipha. ), uma ukumelana okukaliwe kukuncane kunokumelana nokulinganisa, ngokuvamile akunakwa.Ngale ndlela, konke ukumelana ebhodini lesifunda kulinganiswa kanye, ngisho noma inkulungwane eyodwa "ibulawa ngokungalungile", eyodwa ngeke iphuthelwe.
