Inzwa yendawo yokumelana

1.Izinzwa zokuma kokumelana, ngezinye izikhathi ezibizwa ngokuthi ama-potentiometers noma iziguquli zendawo, zifaka izinhlobo eziqondile nezijikelezayo. Ekuqaleni zenzelwe ukusetshenziswa kwezempi, zisetshenziswa kakhulu ukulungisa ama-knob kumisakazo, kumathelevishini noma kumaphaneli okulawula.

2.I-potentiometer iyisisetshenziswa esingenzi lutho futhi ayidingi ukunikezwa kwamandla engeziwe nokusekelwa kwesekethe. I-potentiometer inezinhlobo ezimbili zokusebenza: ukuhlukaniswa kwe-voltage kanye nokumelana okuguquguqukayo. Uma isetshenziswa njenge-resistor eguquguqukayo, ukumelana kwayo kushintsha nendawo yesiphetho esishelelayo, futhi isiphetho esinqunyiwe nesiphetho sokushelela kusetshenziswa lapho kusebenza. Uma isetshenziswa kusihlukanisi se-voltage, iwukusetshenziswa okuvame kakhulu kwe-potentiometer.

I-3.I-voltage yereferensi yokuphumayo itholakala ngokuhlukanisa isici sokumelana. Isimo somzimba sokuphela kokuslayida singatholwa ngokuya ngetiyori yokuhlukaniswa kwe-voltage ye-resistor yochungechunge kanye ne-voltage ephumayo ehlehlayo. Ihlanganisa isekethe ye-amplifier yokusebenza kanye nenzwa yendawo ye-potentiometer, futhi i-voltage ephumayo ibonisa indawo yesiphetho sokuslayida.

4.Ezimweni eziningi, ama-potentiometer asetshenziswa njengezinzwa zokuma. Ineziphetho ezimbili ezingaguquki kanye nesiphetho esishelelayo, futhi isiphetho esishelelayo sixhunywe ngaphandle ngokusebenzisa i-shaft yokudlulisela eyimishini. Imodeli yokunyakaza ingaba ngomugqa noma ngokuzungeza. Lapho ukuphela kokuslayida kuhamba, kuzoshintsha ukumelana phakathi kwamaphethelo amabili agxilile. I-voltage ephumayo ivamise ukulingana nokugudluzwa kokuphela kokuslayida, noma ukumelana nesiphetho sokuslayida kanye nesiphetho esingashintshi silingana nokugudluzwa.

5.Ama-Potentiometers afika ngosayizi nezinhlobo eziningi, futhi ezimbili ezivame ukusetshenziswa kakhulu ziyi-rotary ne-linear. Uma isetshenziswa njengenzwa yendawo, isiphetho sayo sokuslayida ngokuvamile sixhunywa nento etholiwe. Lapho usebenza, i-voltage yereferensi engaguquki idinga ukusetshenziswa emikhawulweni emibili engashintshi ye-potentiometer. I-voltage iphuma kutheminali eshelelayo kanye netheminali engaguquki, okungukuthi, i-voltage ephumayo ihlobene nendawo yetheminali eshelelayo.
