Yuav ua li cas txiav txim siab qhov zoo thiab qhov tsis zoo ntawm lub capacitor yam tsis muaj multimeter
Peb feem ntau siv multimeter los ntsuas qhov tseem ceeb xws li voltage, tam sim no, tsis kam, thiab capacitance. Peb tuaj yeem txiav txim siab qhov zoo thiab qhov tsis zoo ntawm lub capacitor yam tsis muaj multimeter?
Qee yam ntawm peb cov capacitors muaj polarity, thaum lwm tus tsis paub qhov txawv polarity.
1. Polarity insensitive capacitance
Peb feem ntau CBB capacitors, ceramic capacitors, thiab polyester capacitors tsis muaj polarity sib txawv, thiab polarity tsis tas yuav tsum tau muab coj mus rau hauv tus account thaum siv lawv.
2. Polarity distinguishing capacitors
Khoom lub xeev capacitors. Khoom lub xeev capacitors tuaj yeem paub qhov txawv raws li cov cim ntawm lub capacitor casing, nrog cov ntug dub qhia qhov tsis zoo electrode lossis luv luv capacitor tus pin qhia qhov tsis zoo electrode.
Aluminium electrolytic capacitor. Yuav muaj lub cim "-" cim rau ntawm lub plhaub sab nraud ntawm lub capacitor, nrog rau ib sab uas cim tias tsis zoo electrode.
Tantalum electrolytic capacitor. Sab ntawm lub plhaub capacitor nrog cov xim tsaus nti yog qhov zoo electrode.
Thaum siv cov capacitors ua cov khoom tseem ceeb hauv circuits, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo saib thiab xaiv qhov tseeb capacitor tsis raws li cov yam ntxwv sib txawv. Qhov sib txawv ntawm qhov zoo thiab qhov tsis zoo yog feem ntau ua raws li cov txheej txheem no.
AC capacitors tsis paub qhov txawv ntawm qhov zoo thiab qhov tsis zoo, xws li ib-theem lub cev muaj zog pib capacitors, lub tshuab ntxhua khaub ncaws pib capacitors, hluav taws xob kiv cua pib capacitors, lub teeb txuag hluav taws xob damping step-down capacitors, thiab lwm yam. paub qhov txawv ntawm qhov zoo thiab qhov tsis zoo polarity. Cov cai siv feem ntau yog ACxx micro txoj kev, uas tsis tas yuav paub qhov txawv ntawm cov ncej zoo thiab tsis zoo. Tom qab kho lub zog AC ntawm TV, Dv, recorders, thiab lub teeb txuag hluav taws xob, DC voltage tso zis yog siv los ua DC capacitor, uas feem ntau yog cim raws li DCx × Micro method labeling, feem ntau lub plhaub tsis zoo electrode yog cim nrog " ib qho "cim npe, uas sib raug rau qhov tsis zoo electrode ntawm lub capacitor, thiab lwm yam ko taw yog qhov zoo electrode, uas tuaj yeem nkag siab yooj yim yam tsis muaj multimeter.
Cia li saib qhov tsos, cia kuv qhia koj yuav ua li cas saib tom ntej.
Capacitor muab faib ua polar thiab tsis polar capacitor. Tsis yog polar capacitors tsis paub qhov txawv ntawm qhov zoo thiab qhov tsis zoo, thaum tsuas yog polar capacitors paub qhov txawv ntawm qhov zoo thiab qhov tsis zoo.
