ISIZUNGUKO sikagesi
Ngaphandle kokuzama ukwenza umuntu osebenza ngogesi kunoma ubani, ake sihlole izisekelo zesekethe kagesi.Ngaphandle uma ukwazi lokhu, imiqondo efana nendawo kagesi kanye nesekhethi emfishane izobe ingaziwa kuwe, futhi ungase uphuthelwe okuthile okusobala lapho uxazulula inkinga kagesi.
Igama elithi isiyingi livela kumbuthano, futhi elikushoyo ngokwezinto ezibonakalayo ukuthi kufanele kube nokuxhumana okuvela emthonjeni wamanje kuya kubasebenzisi bamanje, bese kubuyela emthonjeni.Ugesi uhamba ohlangothini olulodwa kuphela, ngakho ucingo oluya emthonjeni alukwazi ukusetshenziswa njengendlela yokubuyisela.
Isifunda esilula siboniswa ku-l-10.I-Curent ishiya itheminali kubhethri futhi idlule ocingweni iye kusibani sokukhanya, idivayisi ekhawulela ukugeleza kwamanje ngokucijile kangangokuthi intambo engaphakathi kwesibani iyashisa futhi ikhanye.Lapho i-current idlula ocingweni oluvimbelayo (ebizwa ngokuthi i-filament in the light bull)), iqhubeka ngesegimenti yesibili yocingo ibuyele kutheminali yesibili kubhethri.
Uma noma iyiphi ingxenye yesekethe iphukile, ukugeleza kwamanje kuyama futhi isibani ngeke sikhanyise.Ngokuvamile intambo iyasha ekugcineni, kodwa isibani futhi ngeke sikhanyise uma ingxenye yokuqala noma yesibili yentambo phakathi kwebulb nebhethri iphuka.Qaphela ukuthi noma intambo esuka kubhethri iye kubhalbhu ibingaguquki, isibani besingeke sisebenze uma intambo yokubuyisela iphuka.Ikhefu noma iyiphi indawo kusekethe ibizwa ngokuthi i-open circuit;ukuphuka okunjalo kuvame ukuvela ku-wiring.Izintambo ngokuvamile zimbozwa ngezinto ezivikelayo ukuze zibambe ugesi, ngakho-ke uma izintambo zensimbi ngaphakathi (ezibizwa ngokuthi i-conductor) bezingagqashuka, ungase ungayiboni inkinga ngokubuka nje ucingo.
