Menene alamar microfarads akan multimeter?

Idan kai ma'aikaci ne ko kuma fara da wutar lantarki, kana buƙatar sanin nau'ikan lantarki daban-daban. Daya daga cikin wadannan shi ne microfarad.

So Menene alamar microfarads akan multimeter?? Bari mu amsa wannan tambayar.

A ina muke amfani da microfarads?

Ana amfani da Microfarads a cikin kewayon kayan aikin lantarki, gami da capacitors, transistor, da na'urori masu haɗaka.

Amma mafi sau da yawa za ku ci karo da su lokacin auna ƙarfin capacitor.

Menene capacitor?

Capacitor wani abu ne na lantarki wanda ake amfani dashi don adana cajin lantarki. Ya ƙunshi faranti biyu na ƙarfe waɗanda aka sanya su kusa tare da wani abu mara amfani (wanda ake kira dielectric) a tsakani.

Lokacin da wutar lantarki ta wuce ta capacitor, yana cajin faranti. Ana iya amfani da wannan makamashin lantarki da aka adana don kunna na'urorin lantarki.

Ana amfani da capacitors a cikin kewayon na'urorin lantarki, gami da kwamfutoci, wayoyin hannu, da rediyo.

Akwai manyan nau'ikan capacitors guda biyu:

Polar Capacitors

Polarized capacitors wani nau'in capacitors ne na electrolytic da ke amfani da electrolyte don samar da hanya ga electrons. Ana amfani da irin wannan nau'in capacitor a aikace-aikace iri-iri da suka haɗa da samar da wutar lantarki, sadarwa, ƙaddamarwa, da tacewa.

Electrolytic capacitors yawanci ya fi girma kuma suna da mafi girma capacitance fiye da sauran nau'ikan capacitors.

Mara iyaka capacitor

Non-polar capacitors wani nau'in capacitor ne wanda ke adana makamashi a cikin wutar lantarki. Wannan nau'in capacitor ba shi da na'urar lantarki ta polarizing, don haka filin lantarki yana da simmetrical.

Ana amfani da capacitors marasa iyaka a cikin na'urori daban-daban, ciki har da rediyo, talabijin, da sauran kayan lantarki.

Menene tashoshin capacitor?

Capacitor yana da tashoshi biyu: tabbataccen tasha da mara kyau. Madaidaicin tasha yawanci ana yi masa alama da alamar "+", da kuma mummunan tasha tare da alamar "-".

An tsara tashoshi don haɗa capacitor zuwa da'irar lantarki. An haɗa madaidaicin madaidaicin zuwa wutar lantarki kuma an haɗa tashar mara kyau zuwa ƙasa.

Yadda ake karanta capacitor?

Don karanta capacitor, kuna buƙatar sanin abubuwa biyu: ƙarfin lantarki da ƙarfin aiki.

Voltage shine adadin bambancin yuwuwar wutar lantarki tsakanin ingantattun tashoshi masu kyau da mara kyau na capacitor. Capacitance shine ikon capacitor don adana cajin lantarki.

Yawanci ana rubuta ƙarfin lantarki akan capacitor, yayin da yawanci ana rubuta capacitance a gefen capacitor.

Alamar Microfarad akan multimeter

Alamar microfarads ita ce "uF", wanda zaku samu akan bugun kiran multimeter na ku. Hakanan kuna iya ganin an rubuta a matsayin "uF". Don auna a cikin microfarads, saita multimeter zuwa matsayin "uF" ko "uF".

Madaidaicin naúrar don capacitance shine farad (F). Microfarad shine miliyan ɗaya na farad (0.000001 F).

Ana amfani da microfarad (µF) don auna ƙarfin kayan lantarki ko kewaye. Ƙarfin wutar lantarki ko kewaye shine ikon adana cajin lantarki.

Tunani na asali game da rukunin Farad

Farad shine naúrar ma'auni don ƙarfin aiki. Ana kiran ta da sunan masanin kimiyyar lissafi dan kasar Ingila Michael Faraday. Farad yana auna yawan cajin lantarki da aka adana akan capacitor.

A cikin tebur za ku iya ganin raka'o'in farad daban-daban, da kuma adadinsu.

Capacitance darajar a farads

Yadda za a auna microfarad?

Don gwada capacitance na capacitor, kuna buƙatar multimeter mai iya auna microfarads. Yawancin multimeters masu arha ba su da wannan fasalin.

Kafin aunawa, tabbatar da fitar da capacitor don kada ya lalata multimeter.

Da farko gane tabbatacce da korau tashoshi na capacitor. A kan ma'auni mai ƙarfi, ɗaya daga cikin tasha za a yiwa alama "+" (tabbatacce) da ɗayan "-" (mara kyau).

Sa'an nan haɗa multimeter kai zuwa capacitor tashoshi. Tabbatar cewa an haɗa binciken baƙar fata zuwa madaidaicin madaidaicin kuma jan binciken yana da alaƙa da tabbataccen tasha.

Yanzu kunna multimeter ɗin ku kuma saita shi don auna microfarads (uF). Za ku ga karatun a cikin microfarads akan nuni.

Yanzu da kuka san menene alamar microfarad da yadda ake auna su, zaku iya fara amfani da su a cikin ayyukan ku na lantarki.

Nasihun Tsaro Lokacin Gwaji Capacitors

Auna capacitors yana buƙatar wasu matakan kiyayewa.

Tare da kulawa da tunani, zaku iya auna capacitors ba tare da lalata na'urar da ta auna su ko kanku ba.

• Saka safar hannu masu kauri don kare hannayenku.
• Idan capacitor yana danna jikinka (misali, lokacin auna shi a bayan amplifier ko wani wuri mai matsewa), tsaya akan busasshiyar wuri mai rufi (kamar tabarma na roba) don guje wa girgiza wutar lantarki.
• Yi amfani da daidaitaccen, ingantacciyar ƙirar voltmeter na dijital saiti zuwa madaidaicin kewayo. Kar a yi amfani da na'urar voltmeter na analog (mai nuna motsi) wanda babban igiyoyin ruwa zai iya lalacewa yayin gwada masu iya aiki.
• Idan ba ku da tabbacin idan capacitor ya zama polarized (yana da + da - tashoshi), duba bayanan bayanan sa. Idan takardar bayanan ta ɓace, ɗauka ya zama polarized.
• Kar a haɗa capacitor kai tsaye zuwa tashoshin samar da wutar lantarki saboda hakan na iya lalata capacitor.
• Lokacin auna wutar lantarki ta DC a kan capacitor, ku sani cewa voltmeter kanta zai shafi karatun. Don samun ingantaccen karatu, da farko auna wutar lantarki tare da gajerun wayoyi na mita, sannan ka cire wannan “bised” ƙarfin lantarki daga karatun tare da wayoyi na mita da aka haɗa da capacitor.
