Yuav ua li cas los txiav txim qhov zoo thiab tsis zoo terminals ntawm lub capacitor tsis muaj multimeter?
Peb feem ntau siv multimeters los ntsuas qhov tseem ceeb xws li voltage, tam sim no, tsis kam, thiab capacitance. Yog li cas 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, thiab qee cov capacitors tsis paub qhov txawv polarity.
1. Capacitors uas tsis paub qhov txawv polarity
Peb feem ntau CBB capacitors, ceramic capacitors, thiab polyester capacitors tsis muaj polarity txawv, yog li koj tsis tas yuav xyuam xim rau polarity thaum siv lawv.
2. Ntsuas qhov polarity ntawm capacitors
Khoom capacitor. Khoom capacitor tuaj yeem paub qhov txawv raws li qhov cim ntawm lub plhaub capacitor. Lub ntug dub ntawm lub plhaub yog tus ncej tsis zoo, lossis tus pin luv capacitor yog tus ncej tsis zoo.
Aluminium electrolytic capacitor. Yuav muaj lub cim "-" cim rau ntawm lub capacitor lub plhaub, thiab sab cim yog tus ncej tsis zoo.
Thaum siv cov capacitor ua ib qho tseem ceeb ntawm lub voj voog, ua tib zoo xaiv cov khoom capacitor kom raug 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 polarities. Piv txwv li, ib-theem lub cev muaj zog pib capacitors, tshuab ntxhua khaub ncaws pib capacitors, hluav taws xob kiv cua pib capacitors, lub zog txuag teeb damping puck capacitors, thiab lwm yam yog tag nrho cov AC capacitors. Lawv tsis paub qhov txawv ntawm qhov zoo thiab qhov tsis zoo polarity. Cov cai tshaj plaws yog: ACxx microfarads, tsis tas yuav tsum paub qhov txawv ntawm cov ncej zoo thiab tsis zoo. TVs, Dvs, cassette players, thiab lub teeb txuag hluav taws xob siv DC capacitors los tso tawm DC voltage tom qab kho qhov hloov tam sim no. Nws feem ntau cim DCx × microfarads. Feem ntau, lub plhaub tsis zoo electrode yog cim nrog "- Peugeot, qhov tsis zoo no sib raug rau tus ncej tsis zoo ntawm lub capacitor, thiab lwm ceg yog tus ncej zoo, koj tuaj yeem pom nws ntawm ib nrais muag yam tsis siv lub tshuab multimeter.
