1, Uyini umehluko phakathi kokuvuza kwamanje okukalwa ukuhlolwa kwe-voltage ukumelana nokuhlolwa kokuvuza kwamandla?
Ukuhlolwa kwe-voltage ye-standard kutholwe umthamo wamanje oweqisayo ogeleza ohlelweni lokufakwa ngaphakathi ngenxa yezimo zokugcwala ngokweqile ngamabomu.Ukuhlolwa kokuvuza kwesekethe nakho kuthola ukuvuza kwamanje, kodwa hhayi ngaphansi kwe-voltage ephezulu yokuhlolwa kwe-voltage yokumelana, kodwa ngaphansi kwe-voltage evamile yokusebenza kwamandla kagesi.Ikala inani lamanje eligeleza ngokucindezela komzimba womuntu olingisiwe lapho i-DUT ivuliwe futhi isebenza.
2, Kungani amanani wamanje okuvuza akalwa kusetshenziswa i-AC ne-DC ukumelana nokuhlolwa kwamandla kagesi ehluka?
Amandla alahlekile ento ehloliwe yisizathu esiyinhloko somehluko kumanani akalwayo phakathi kwe-AC ne-DC ukumelana nokuhlolwa kwe-voltage.Uma kuhlolwa nge-AC, kungase kungenzeki ukushaja ngokugcwele lawa ma-capacitor alahlekile futhi kuzoba khona imanje eqhubekayo egeleza kuwo.Uma usebenzisa ukuhlola kwe-DC, uma amandla alahlekile entweni ehloliwe eseshajwe ngokugcwele, inani elisele liwukuvuza kwamanje kwento ehloliwe.Ngakho-ke, amanani wamanje wokuvuza akalwa kusetshenziswa i-AC ukumelana nokuhlolwa kwamandla kagesi kanye ne-DC ukumelana nokuhlolwa kwamandla kagesi azohluka.
