ISEKELA WOMbane
Ngaphandle kokuzama ukwenza umntu osebenza ngombane kuye nabani na, makhe sibaleke ngokukhawuleza kwiziseko zombane.Ngaphandle kokuba uyayazi le nto, iikhonsepthi ezinjengendawo yombane kunye nesekethe emfutshane ziya kuba yinto engaqhelekanga kuwe, kwaye unokuphoswa yinto ecacileyo xa ulungisa ingxaki yombane.
Igama elithi isekethe lisuka kwisangqa, kwaye lithetha ukuthini ngokwemigaqo esebenzayo kukuba kufuneka kubekho unxibelelwano olusuka kumthombo wangoku ukuya kubasebenzisi bomjelo, emva koko ubuyele kumthombo.Umbane uhamba kwicala elinye kuphela, ngoko ke ucingo oluya kumthombo alunakusetyenziswa njengembuyekezo.
Isekethe elula kakhulu iboniswe kwi-l-10.I-current ishiya i-terminal kwibhetri kwaye idlula ngocingo ukuya kwibhalbhu yesibane, isixhobo esinqanda ukuhamba kwangoku kabukhali ukuze ucingo olungaphakathi kwibhalbhu lube shushu kwaye lubengezele.Xa i-current idlula kwi-restricting wire (ebizwa ngokuba yi-filament kwinkunzi yenkomo)), iqhubeka ngecandelo lesibini locingo ukubuyisela kwi-terminal yesibini kwibhetri.
Ukuba nayiphi na inxalenye yesekethe iphukile, ukuhamba kwangoku kuyeka kwaye ibhalbhu ayiyi kukhanya.Ngokuqhelekileyo i-filament iyatsha ekugqibeleni, kodwa ibhalbhu nayo ayinakukhanya ukuba inxalenye yokuqala okanye yesibini yocingo phakathi kwebhalbhu nebhetri yophukile.Qaphela ukuba nokuba ucingo olusuka kwibhetri ukuya kwibhalbhu belugqibelele, ibhalbhu ibingenakusebenza ukuba ucingo lokubuya luqhawukile.Ikhefu nayiphi na indawo kwisekethe ibizwa ngokuba yi-open circuit;ezo zaphulelo zikholisa ukwenzeka kwiingcingo.Iingcingo ngokuqhelekileyo zigqunywa ngezinto zokugquma ukuze zibambe umbane, ngoko ke ukuba imisonto yentsimbi engaphakathi (ebizwa ngokuba yi-conductor) ibinokwaphuka, usenokungayiboni ingxaki ngokujonga nje ucingo.
