Ukhuseleko lwangoku kunye nombane okhuselekileyo
Ngokuqhelekileyo, umzimba womntu unokuva ixabiso langoku lokuvuselela malunga ne-1 mA.Xa umzimba womntu udlula i-5 ~ 20mA, izihlunu ziya kuncipha kwaye zixube, ukuze umntu angakwazi ukuhlukana nocingo.Imveliso yokothuka kombane yangoku kunye nexesha elivunyelweyo ...Funda ngokugqithisileyo -
Intshayelelo kwizinto eziluncedo kunye nezingeloncedo zokumelana novavanyo lombane
Ukungalungi kovavanyo oluthe ngqo lwangoku (DC) (1) Ngaphandle kokuba akukho capacitance kwinto elinganisiweyo, i-voltage yokuvavanya kufuneka iqale ukusuka "ku-zero" kwaye inyuke ngokucothayo ukuphepha ukutshaja ngokugqithisileyo.I-voltage eyongeziweyo nayo iphantsi.Xa umsinga wokutshaja mkhulu kakhulu, uya kuchaza...Funda ngokugqithisileyo -
Imiba yonyango lokumelana nesixhobo sombane
Imiqathango yonyango lokumelana novavanyo lombane Uvavanyo lokumelana nombane sisixhobo esisetyenziselwa ukulinganisa amandla okumelana noxinzelelo lweenkqubo zonyango kunye nezixhobo zonyango.Iyakwazi ukuvavanya intuitively, ngokuchanekileyo, ngokukhawuleza nangokuthembekileyo umbane wokuqhekeka, ...Funda ngokugqithisileyo -
Earth Resistance Test
Igama elithi "ukuchasa umhlaba" ligama elingachazwanga kakuhle.Kweminye imigangatho (efana nemigangatho yokhuseleko yezixhobo zendlu), ibhekisa kuxhathiso lwesiseko ngaphakathi kwesixhobo, ngelixa kweminye imigangatho (efana nekhowudi yoyilo lomgangatho), ibhekisa kuxhathiso lwe ...Funda ngokugqithisileyo -
Ukuvuza uvavanyo lwangoku
Ukuvuza kwangoku kwezixhobo zendlu kubhekiselele kumbane ovuzayo olinganiswa nesixhobo sombane phantsi kwesenzo sombane.Uza kuvavanywa.Umgaqo wovavanyo kukulinganisa i-impedance yomzimba womntu.Funda ngokugqithisileyo -
Amandla e-Dielectric (ukumelana ne-voltage) uvavanyo
Uvavanyo lwamandla ombane, olwaziwa ngokuba luvavanyo lokumelana nombane, ngumlinganiselo wokukwazi ukugquma umbane ukuze umelane nokuqhekeka phantsi kwesenzo sombane ogqithisileyo.Ikwayindlela ethembekileyo yokuvavanya ukuba imveliso ikhuselekile na ukuyisebenzisa.Pha...Funda ngokugqithisileyo
