1, Uthini umahluko phakathi kokuvuza kwangoku okulinganiswa novavanyo lokumelana nombane kunye novavanyo lokuvuza kwamandla?
Uvavanyo lokumelana ne-voltage luchonge umsinga ogqithisayo oqukuqelayo kwisixokelelwano sokugquma ngenxa yeemeko zokugqithisa ngabom.Uvavanyo lokuvuza kwesekethe lukwafumanisa ukuvuza kwangoku, kodwa hayi phantsi kombane ophezulu wovavanyo lokumelana nombane, kodwa phantsi kombane osebenzayo oqhelekileyo wonikezelo lwamandla.Ilinganisa ubungakanani bokuqukuqela kwangoku kuthintelo lomzimba womntu ofanisiweyo xa i-DUT ilayita kwaye isebenza.
2, Kutheni ukuvuza kwangoku amaxabiso alinganiswa usebenzisa i-AC kunye ne-DC ukumelana novavanyo lombane lohluka?
I-capacitance elahlekileyo yento evavanyiweyo sesona sizathu siphambili somahluko kumaxabiso alinganisiweyo phakathi kwe-AC kunye ne-DC yokumelana novavanyo lombane.Xa uvavanya nge-AC, akunakwenzeka ukuba uhlawule ngokupheleleyo la ma-capacitors alahlekileyo kwaye kuya kubakho umbane oqhubekayo ohamba ngawo.Xa usebenzisa uvavanyo lwe-DC, xa i-capacitance elahlekileyo kwinto evavanyiweyo ihlawuliswe ngokupheleleyo, isixa esisele sisona sikhoyo sokuvuza sangoku sento evavanyiweyo.Ke ngoko, amaxabiso akhoyo avuzayo alinganiswa kusetyenziswa uvavanyo lwe-AC lokumelana nombane kunye ne-DC yokumelana novavanyo lombane luya kwahluka.
