Potentiometers, Trimmers & Rheostats

Potentiometers, trimmers, thiab rheostats yog txhua hom kev sib txawv ntawm cov resistors, tab sis lawv ua hauj lwm me ntsis txawv lub hom phiaj: Potentiometers (Cas): Muaj nuj nqi: Potentiometers yog qhov sib txawv ntawm cov resistors uas tso cai rau kev hloov kho ntawm kev tiv thaiv raws txoj kev txuas mus ntxiv. Kev tsim kho: Lawv muaj cov khoom tiv thaiv thiab lub wiper, uas ua rau kev sib cuag nrog cov khoom siv tiv thaiv. Kev Siv: Cov lauj kaub feem ntau yog siv los tswj lub ntim hauv cov khoom siv suab, dimmer keyboards hauv teeb pom kev zoo, thiab lwm yam kev siv uas yuav tsum tau hloov kho kom du thiab txuas ntxiv. Trimmers (Trim Pots or Trimpots): Function: Trimmers yog hom potentiometer, tab sis lawv tau tsim los rau kev hloov kho tsis tu ncua. Lawv feem ntau siv rau qhov pib calibrations lossis chaw uas tsis tas yuav hloov pauv ntau zaus. Kev tsim kho: Cov trimmers zoo ib yam li cov lauj kaub tab sis feem ntau me dua thiab txuas ncaj qha rau ntawm lub rooj tsav xwm Circuit Court. Kev Siv: Cov trimmers feem ntau pom muaj nyob rau hauv hluav taws xob circuits rau kev kho kom zoo lossis ntsuas qhov tshwj xeeb thaum tsim khoom. Rheostats: Muaj nuj nqi: Rheostats yog qhov sib txawv ntawm cov resistors siv los kho tam sim no hauv Circuit Court. Tsis zoo li cov lauj kaub thiab cov trimmer, lawv feem ntau yog tsim los rau kev siv hluav taws xob ntau dua. Kev tsim kho: Rheostats muaj cov hlau tiv thaiv qhwv ib ncig ntawm lub kauj, thiab lub wiper uas txav raws lub kauj los kho qhov kev tiv thaiv. Kev Siv: Rheostats feem ntau siv rau hauv cov ntawv thov xws li kev tswj xyuas lub cev muaj zog, cov khoom cua sov, lossis txhua qhov xwm txheej uas qhov sib txawv ntawm qhov tam sim no yog qhov tseem ceeb. Hauv cov ntsiab lus, thaum tag nrho peb yog hom kev sib txawv ntawm cov resistors, potentiometers muaj ntau yam thiab siv rau kev hloov kho tsis tu ncua, trimmers yog rau kev hloov kho tsis tu ncua, thiab rheostats yog tsim los rau kev siv hluav taws xob ntau dua qhov kev tswj tam sim no tseem ceeb heev.
