Waa maxay calaamada microfarads-ka ee multimeter-ka?

Haddii aad tahay koronto-yaqaan ama aad hadda bilaabayso koronto, waxaad u baahan tahay inaad ka warqabto qaybaha kala duwan ee korontadu. Mid ka mid ah kuwan waa microfarad.

So Waa maxay calaamada microfarads-ka ee multimeter-ka?? Aan ka jawaabno su'aashan.

Halkee ayaan ka isticmaalnaa microfarad?

Microfarads waxaa loo isticmaalaa qalabyo kala duwan oo elegtaroonig ah, oo ay ku jiraan capacitors, transistors, iyo wareegyada isku dhafan.

Laakiin inta badan waxaad la kulmi doontaa iyaga marka la cabbirayo capacitance capacitor ah.

Waa maxay capacitor?

Capacitor waa qayb elektaroonik ah oo loo isticmaalo in lagu kaydiyo kharashka korontada. Waxay ka kooban tahay laba taariko bir ah oo isku dhow oo ay weheliyaan wax aan shaqaynayn (oo loo yaqaan dielectric) inta u dhaxaysa.

Marka korantada korantada ay dhex marto capacitor-ka, waxay dalacaysaa taarikada. Tamartan korantada ee la kaydiyay ayaa markaa loo isticmaali karaa in lagu shubo qalabka elegtarooniga ah.

Capacitors waxaa loo isticmaalaa qalabyo kala duwan oo elegtaroonig ah, oo ay ku jiraan kombuyuutar, telefoonada gacanta, iyo raadiyaha.

Waxaa jira laba nooc oo waaweyn ee capacitors:

Capacitors Polar

Capacitors Polar waa nooc ka mid ah capacitors electrolytic kuwaas oo isticmaala electrolyte si ay u bixiyaan waddo loogu talagalay electrons. Capacitor-ka noocaan ah waxaa loo isticmaalaa codsiyo kala duwan oo ay ku jiraan sahay koronto, isgaarsiin, kala furfurid, iyo shaandheyn.

Dabaylayaasha korantada ayaa badanaa ka weyn waxayna leeyihiin awood sare marka loo eego noocyada kale ee capacitors.

Capacitor-ka aan dabaylaha ahayn

Capacitors non-polar waa nooc ka mid ah capacitor oo tamarta ku kaydiya goobta korantada. Capacitor-ka noocaan ah ma laha korantada polarizing, sidaas darteed goobta korontadu waa mid simmetrical ah.

Capacitors non-polar waxaa loo isticmaalaa qalab kala duwan, oo ay ku jiraan raadiyaha, telefishinada, iyo qalabka kale ee elegtarooniga ah.

Waa maxay terminaalka capacitor?

Capacitor-ku wuxuu leeyahay laba terminal: Terminal togan iyo mid taban. Terminalka togan waxaa badanaa lagu calaamadeeyaa calaamad "+", halka taarka xunna lagu calaamadeeyay calaamad "-".

Terminal-yada waxaa loogu talagalay inay ku xiraan capacitor-ka wareegga korantada. Terminal-ka togan wuxuu ku xiran yahay korontadda iyo terminalka taban wuxuu ku xiran yahay dhulka.

Sidee loo akhriyaa capacitor?

Si aad u akhrido capacitor, waxaad u baahan tahay inaad ogaato laba shay: Voltage iyo capacitance.

Voltage waa qadarka farqiga awooda korantada ee u dhexeeya terminaalka togan iyo kuwa taban ee capacitor. Capacitance waa awooda capacitor si uu u kaydiyo kharash koronto.

Voltage inta badan waxa lagu qoraa capacitor-ka, halka awood-qaadashaduna ay inta badan ku qoran tahay dhinaca capacitor-ka.

Calaamada Microfarad oo ku taal multimeter

Calaamadda microfaradku waa "uF", kaas oo aad ka heli doonto garaaca mitirkaaga. Waxa kale oo aad arki kartaa in ay u qoran tahay "uF". Si aad u cabbirto microfarad, u dhig multimeterka booska "uF" ama "uF".

Cutubka caadiga ah ee awood-qaadista waa farad (F). Microfarad waa hal milyan oo farad (0.000001 F).

Microfarad (µF) ayaa loo isticmaalaa in lagu cabbiro awoodda qayb koronto ama wareeg ah. Awoodda qayb ka mid ah korantada ama wareegga waa awoodda lagu kaydiyo kharashka korontada.

Fikradaha aasaasiga ah ee ku saabsan cutubka Farad

Farad waa halbeeg cabbirka awoodda. Waxaa loogu magac daray Fiisigiste Ingiriis ah Michael Faraday. Faradku wuxuu cabbiraa inta koronto ee ku kaydsan capacitor-ka.

Shaxda waxaad ka arki kartaa qaybaha kala duwan ee faradka, iyo sidoo kale saamigooda.

имя	astaamaha	Isbedelka	Tusaale
picofara	pF	1pF = 10-12F	C=10 pF
нФ	nF	1 nF = 10-9F	C=10 nF
microwave ka	uF	1µF = 10-6F	C=10uF
millifarad	mF	1 mF = 10-3F	C=10mF
farada	F	S=10F
kilofarad	kF	1kF=103F	C=10kF
megatariffs	MF	1MF=106F	S=10MF

Qiimaha awoodda ee farads

Sidee loo cabbiraa microfarad?

Si aad u tijaabiso awoodda capacitor, waxaad u baahan doontaa multimeter awood u leh in lagu cabbiro microfarad. Inta badan mitirka raqiis ah ma laha sifadan.

Kahor intaadan cabbirin, hubi inaad soo daysay capacitor-ka si uusan u dhaawicin multimeter-ka.

Marka hore cadee terminaalka togan iyo kuwa taban ee capacitor-ka. Kapacitor-ku-salaysan, mid ka mid ah terminaalka waxa lagu calaamadayn doonaa "+" (positive) iyo kan kale "-" (negative).

Kadibna ku xidh hagaha multimeter-ka ilaa terminaalka capacitor-ka. Hubi in baaritaanka madow uu ku xiran yahay terminaalka taban iyo baaritaanka cas uu ku xiran yahay terminalka togan.

Hadda shid multimeter-kaaga oo dhig si aad u cabbirto microfarads (uF). Waxaad arki doontaa wax-akhrinta ee microfarad shaashadda.

Hadda oo aad ogtahay waxa calaamadda microfarad ay tahay iyo sida loo cabbiro, waxaad bilaabi kartaa iyaga oo isticmaalaya mashaariicda korontada.

Talooyin Badbaadada Marka la tijaabinayo Capacitors

Cabbiraadda capacitors waxay u baahan tahay taxaddar.

Taxadir iyo ka fiirsasho, waxaad ku cabbiri kartaa capacitors adiga oo aan waxyeello u geysan qalabka cabbiraya iyaga ama laftaada.

• Xidho galoofyada qaro weyn si aad u ilaaliso gacmahaaga.
• Haddii capacitor-ku lagu cadaadiyo jidhkaaga (tusaale, marka lagu cabbirayo xagga dambe ee cod-weyneeye ama meel kale oo cidhiidhi ah), ku istaag meel engegan oo daboolan (sida gogosha cinjirka) si aad uga fogaato shoog koronto.
• Isticmaal voltmeter dhijitaal ah oo sax ah, si fiican loo calamey oo lagu dejiyay xadka saxda ah. Ha isticmaalin voltmeter-ka analooga ah (tilmaamaha dhaqaaqa) kaas oo laga yaabo in ay waxyeelo ka soo gaarto qulqulka sare marka la tijaabinayo capacitors.
• Haddii aadan hubin in capacitor-ku uu yahay polarized (wuxuu leeyahay + iyo - terminal), hubi xaashida xogta. Haddii xaashida xogtu maqan tahay, ka soo qaad in uu yahay mid kala duwan.
• Si toos ah ha ugu xidhin capacitor-ka korantada korantada sababtoo ah taasi waxay dhaawici kartaa capacitor-ka.
• Markaad cabbirayso danab DC ah oo ku dhex jira capacitor, la soco in voltmeterka laftiisu uu saamayn doono akhriska. Si aad u hesho akhris sax ah, marka hore ku cabbir danabka iyadoo ay fiilooyinka mitirku gaaban yihiin, ka dibna ka jar danabkaas “eexda” ah ee akhrinta xargaha mitirka ee ku xidhan capacitor-ka.
