Isixazululo ku- izinga lokushisa eliphezulu lebhokisi-uhlobo lokumelana nesithando somlilo hhayi ukushisisa

① I-voltage yokuphakelwa kwamandla ijwayelekile, isilawuli sisebenza ngokujwayelekile, futhi i-ammeter ayinakho isibonisi. Kungenzeka ukuthi ucingo lwesithando somlilo kagesi wesithando sokushisa esiphezulu sebhokisi-uhlobo lokumelana nesithando somlilo sivulekile, esingase sihlolwe nge-multimeter futhi sithathelwe indawo ngocingo lwesithando somlilo esicacisiwe esifanayo.

②I-voltage yokunikezwa kwamandla ijwayelekile, futhi isilawuli asikwazi ukusebenza. I-switch, i-fuse kanye neswishi yohambo yomnyango wesithando somlilo ingahlolwa futhi ilungiswe ngaphakathi kwesilawuli. Uma umnyango wesithando somlilo kagesi ungavaliwe futhi isilawuli asikwazi ukusebenza, sidinga ukulungiswa ngokwendlela yokulungisa yokuhluleka kwesilawuli.

③Ukuhluleka kokunikezwa kwamandla: kusebenza ngokujwayelekile uma ungaxhumekile esithandweni sikagesi, kodwa akusebenzi ngokujwayelekile uma kuxhunywe esithandweni sikagesi, futhi kunomsindo wokuchofoza okuqhubekayo kusilawuli. Isizathu siwukuthi ukwehla kwe-voltage yesekethe yokuphakelwa kwamandla yesithando somlilo sokumelana nokushisa okuphezulu kohlobo lwebhokisi kukhulu kakhulu, noma isokhethi kanye neswishi yokulawula akuxhumani kahle, okungalungiswa noma kushintshwe.
