Kev txiav txim siab ntawm qhov zoo thiab qhov tsis zoo ntawm lub capacitor yam tsis muaj multimeter
Peb feem ntau siv lub multimeter los ntsuas qhov voltage, tam sim no, tsis kam thiab capacitance thiab lwm yam txiaj ntsig, yog tias tsis muaj multimeter yuav txiav txim siab qhov zoo thiab qhov tsis zoo?
Qee yam ntawm peb cov capacitors muaj polarity, qee cov capacitors tsis paub qhov txawv ntawm polarity.
1. Tsis txhob cais qhov polarity ntawm lub capacitor
Peb feem ntau CBB capacitors, ceramic capacitors, polyester capacitors tsis polarity txawv, kev siv polarity tsis tas yuav xyuam xim rau.
2. Ntsuas qhov polarity ntawm lub capacitor
Khoom lub xeev capacitors. Khoom capacitors tuaj yeem paub qhov txawv raws li lub plhaub capacitor cim, lub plhaub cim nrog dub yog qhov tsis zoo, lossis lub capacitor pin luv yog qhov tsis zoo. Aluminium electrolytic capacitor. Nyob rau hauv lub capacitor plhaub yuav raug cim "-" cim, cim nyob rau sab ntawm tus ncej tsis zoo.
AC capacitors tsis muab faib ua qhov zoo thiab tsis zoo polarity, xws li ib-theem lub cev muaj zog pib capacitors, tshuab ntxhua khaub ncaws pib capacitors, kiv cua pib capacitors, lub zog txuag teeb damping capacitors, thiab lwm yam yog AC capacitors, tsis muab faib ua qhov zoo thiab tsis zoo polarity. , feem ntau siv code yog ACxx microfarad, tsis tas yuav paub qhov txawv ntawm qhov zoo thiab qhov tsis zoo polarity, TV, Dv, recorders, lub zog txuag teeb AC rectified DC voltage tso zis DC capacitors siv, feem ntau cim DCx × microfarad cim nyob! Lub plhaub tsis zoo yog cim nrog "ib qho ntawm cov qauv, qhov tsis zoo no sib raug rau qhov tsis zoo ntawm lub capacitor, lwm yam ko taw yog qhov zoo, tsis tas yuav tsum muaj lub tshuab multimeter ntawm ib nrais muag kom pom kev nkag siab.
Ncaj nraim saib qhov tsos tuaj yeem ua tau, ces qhia koj seb yuav saib li cas.
Capacitor muab faib ua polar capacitance thiab tsis-polar capacitance, tsis-polar capacitance tsis muab faib ua tus ncej zoo thiab tsis zoo, thiab tsuas yog polar capacitance kom paub qhov txawv ntawm cov ncej zoo thiab tsis zoo.
