Ama-resistors angahlukaniswa ngezinhlobo ezimbili eziyinhloko ngokuya ngokuthi inani lokumelana lingashintshwa noma cha: ama-resistors agxilile nama-resistors aguquguqukayo.
I-Fixed Resistors: Inani lokumelana lalezi zinto eziphikisayo linqunywa ngesikhathi sokukhiqiza futhi alishintshi ngaphansi kwezimo ezivamile zokusetshenziswa.Ziwuhlobo oluvame kakhulu lwe-resistor futhi zisetshenziswa ezinhlobonhlobo zamasekhethi ukuze zinikeze inani eliqhubekayo lokumelana.Ama-resistors angaguquki ngokuvamile aneziphetho ezimbili, ezingase zimelelwe kumdwebo wesifunda njengomugqa oqondile, nebanga phakathi kwamaphethelo amabili abonisa inani lawo lokumelana.
Ngokungafani nama-resistors angaguquki, inani lokumelana lama-resistors aguquguqukayo lingashintshwa ngokulungiswa kwangaphandle.Lokhu kuzenza zilungele izinhlelo zokusebenza lapho kudingeka khona ukulawulwa okunembile kwevelu yokumelana.Izinqamuli eziguquguqukayo ngokuvamile ziba namatheminali amathathu kanye nokuxhumana okuslayidayo okungahanjiswa kuwo wonke umzimba ophikisayo ukuze kushintshwe inani lokumelana.Izinhlobo ezivamile zokuphikisa okuguquguqukayo zihlanganisa ama-varistors wezintambo zesilayidi nama-potentiometers.
Ngaphezu kwama-resistor ahleliwe futhi aguquguqukayo, kunohlobo olukhethekile lwe-resistor olubizwa ngokuthi "i-sensitive resistor," engashintsha inani layo lokumelana ngokuphendula izinguquko ezimweni zemvelo (isb., izinga lokushisa, ingcindezi, umswakama, njll.).
Ezingeni lesakhiwo, inani lokumelana le-resistor egxilile linqunywa phakathi nenqubo yokukhiqiza futhi alishintshi ngesikhathi sokuphila kwayo.Ngokuphambene, inani lokumelana le-resistor eguquguqukayo lingalungiswa ngomshini noma ngogesi.Abangaphakathi babo ngokuvamile baqukatha oyedwa noma abaningi abathintwayo abashelelayo noma abazungezisayo kumzimba ophikisayo ukuze kuguqulwe inani lokumelana.
Ama-resistors angaguquki afanele izinhlelo zokusebenza ezidinga ukunemba kumapharamitha wesifunda ngoba anganikeza inani elizinzile lokumelana.Ama-resistors angaguquki anempilo ende yesevisi ngenxa yokunemba kwawo okuphezulu nokuzinza.Ngakolunye uhlangothi, ama-resistors aguquguqukayo asetshenziswa ikakhulukazi lapho ukulungiswa okuguquguqukayo kwevelu yokumelana kuyadingeka.Isibonelo, ukulungisa ivolumu noma ukuguqula izinga lesiginali kumpahla yomsindo, noma ukuzuza ugesi onembile noma isilawuli samanje kumasistimu okulawula okuzenzakalelayo.
Ama-resistors angaguquki kanye nama-resistors aguquguqukayo nawo ahlukile ekwakhiweni nasekukhiqizeni izinqubo.Ama-resistors angaguquki ngokuvamile asebenzisa ubuchwepheshe befilimu emincane noma ifilimu ewugqinsi, lapho izinto zokuqhuba zifakwa ku-substrate ukuze zakhe isiphikisa.Ngakolunye uhlangothi, izinqamuleli eziguquguqukayo, zingadinga izinsimbi eziyinkimbinkimbi ukuze kuqinisekiswe ukuthi abathintwayo bangahamba kahle.Ukukhetha phakathi kweziphikisayo ezingaguquki neziguquguqukayo kuphinde kubandakanye ukuhwebelana phakathi kwezindleko nokusebenza.Ama-resistors angaguquki ngokuvamile awabizi kangako ngoba kulula ukuwenza.
