Ngokuvamile kubonakale ukuthi abaqalayo abaningi baphonsa ngokumelana ngenkathi belungisa umjikelezo, futhi badilizwa futhi badilizwa. Eqinisweni, sekulungisiwe kakhulu. Uma nje uqonda izici zomonakalo zokumelana, akudingeki uchithe isikhathi esiningi.
Ukumelana nengxenye eminingi kakhulu emishini kagesi, kepha akuyona ingxenye enezinga eliphakeme kakhulu lokulimala. Vula umjikelezo luhlobo oluvame kakhulu lokulimala kokumelana. Kuyaqabukela ukuthi inani lokumelana liba likhulu, futhi inani lokumelana liba lincane. Okujwayelekile kufaka phakathi ukumelana kwefilimu yekhabhoni, abamelana nemephu yensimbi, ukumelana kwezilonda zocingo kanye nokuphikiswa komshuwalense.
Izinhlobo ezimbili zokuqala zabaphikisi zisetshenziswa kabanzi. Enye yezimpawu zomonakalo wazo ukuthi izinga lokulimala kokumelana okuphansi (ngezansi kwe-100ω) kanye nokumelana okuphezulu (ngenhla kwe-100kω) kuphakeme, kanye nenani lamakhulu ama-ohms kumashumi ama-kiloohms) umonakalo omncane kakhulu; Okwesibili, lapho ukulimala kokumelana okuphansi kulimele, zivame ukushiswa futhi zimnyama, okulula ukuzithola, ngenkathi ukumelana nokumelana nokuvuselelwa okuphezulu akuvamile ukuba kulinyazwe.
Ukumelana kwe-wirewound ngokuvamile kusetshenziselwa umkhawulo wamanje, futhi ukumelana akukukhulu. Lapho amanxeba e-cylindrical wire wire evutha, amanye azophenduka abe mnyama noma ingaphezulu liqhume noma liqhekeke, kanti abanye ngeke babe nabala. Ukumelana nosimende kuwuhlobo lomhlaseli wenxeba le-wire, okungahle kuphule lapho kushiswe ngaphandle, ngaphandle kwalokho ngeke kube khona iminonjana ebonakalayo. Lapho i-fuse resistor ivutha, ucezu lwesikhumba luzoshaywa khona kwezinye izindawo, futhi abanye abanakho umkhondo, kepha abasoze bashisa noma bajike abamnyama. Ngokusho kwezici ezingenhla, ungagxila ekubhekeni ukumelana futhi uthole ngokushesha ukumelana okulimele.
Ngokusho kwezimpawu ezibalwe ngenhla, okokuqala singaqala ukubona ukuthi ngabe abaphikisi bokumelana okuphansi ebhodini lesekethe bashise amamaki amnyama, bese kuthi ngokwezimpawu iningi labo abaphikisayo ezivulekile noma ukumelana kuba nkulu futhi kulimala kalula. Singasebenzisa i-multimeter ukuze silinganise ngokuqondile ukumelana emikhawulweni yomibili yokumelana nokumelana okuphezulu ebhodini lesekethe. Uma ukumelana okulinganiselwe kukhulu kunokumelana nokungalingani (Qaphela ukuthi ukumelana kuzinzile ngaphambi kokubonisana ngokubonisana, ngoba kungenzeka kube lula ukweqisa kunokuphikiswa okukhohlisayo, ngokuvamile akunakwa. Ngale ndlela, konke ukumelana nebhodi yesekethe kulinganiswa futhi, futhi noma ngabe iyiphi inkulungwane "ebulewe ngokungafanele", umuntu ngeke aphuthelwe.
