Isivivinyo : Ubuqotho bebhuloho
Qinisekisa ubuqotho bebhuloho ngokulinganisa ukumelana nokokufaka nokuphumayo kanye nebhalansi yebhuloho. Nqamula iseli lokulayisha ebhokisini lokuhlangana noma idivayisi yokulinganisa.
Ukumelana nokokufaka nokuphumayo kukalwa nge-ohmmeter kupheya ngayinye yokufaka nemikhondo yokuphumayo. Qhathanisa ukumelana nokokufaka kanye nokuphumayo nesitifiketi sokuqala sokulinganisa (uma sikhona) noma imininingwane yeshidi ledatha.
Ibhalansi yebhuloho itholakala ngokuqhathanisa -okuphumayo kokuthi -kokufaka kanye -okuphumayo +nokumelana nokokufaka. Umehluko phakathi kwamanani amabili kufanele ube ngaphansi noma ulingane no-1Ω.
Hlaziya:
Izinguquko ekumelaneni kwebhuloho noma ibhalansi yebhuloho ngokuvamile zibangelwa izintambo ezinqanyuliwe noma ezishile, izingxenye zikagesi ezinephutha, noma amasekhethi amafushane angaphakathi. Lokhu kungabangelwa ukugcwala ngokweqile (umbani noma ukushisela), ukulimala komzimba okuvela ekushaqekeni, ukudlidliza noma ukukhathala, izinga lokushisa elidlulele noma ukukhiqizwa okungaguquki.
Isivivinyo : Ukumelana Nomthelela
Iseli lomthwalo kufanele lixhunywe kumthombo wamandla ozinzile, okungcono inkomba yeseli yomthwalo enevolthi ye-excitation okungenani engu-10 volts. Nqamula wonke amanye amaseli omthwalo wesistimu yeseli yokulayisha eminingi.
Xhuma i-voltmeter kokuphumayo bese uthepha iseli yokulayisha kancane nge-mallet ukuze idlidlize kancane. Lapho kuhlolwa ukumelana nokushaqeka kwamaseli omthwalo ophansi womthamo, kufanele kuqikelelwe ukuthi ungawalayishi ngokweqile.
Qaphela ukufundwa ngesikhathi sokuhlolwa. Ukufundwa akufanele kuguquke, kufanele kuhlale kuzinzile futhi kubuyele ekufundweni kweziro kwasekuqaleni.
Hlaziya:
Ukufundwa okungaqondakali kungase kubonise uxhumano lukagesi olunephutha noma isibopho esilimele phakathi kwegeji yobunzima kanye nengxenye ngenxa yezinto ezidlulayo zikagesi.
