Kodi chizindikiro cha microfarad pa multimeter ndi chiyani?

Ngati ndinu katswiri wamagetsi kapena mukungoyamba kumene magetsi, muyenera kudziwa zamagulu osiyanasiyana amagetsi. Chimodzi mwa izi ndi microfarad.

So Kodi chizindikiro cha microfarad pa multimeter ndi chiyani?? Tiyeni tiyankhe funso ili.

Kodi timagwiritsa ntchito kuti ma microfarad?

Ma Microfarad amagwiritsidwa ntchito pazida zosiyanasiyana zamagetsi, kuphatikiza ma capacitor, ma transistors, ndi mabwalo ophatikizika.

Koma nthawi zambiri mumakumana nawo poyesa capacitance ya capacitor.

Kodi capacitor ndi chiyani?

Capacitor ndi gawo lamagetsi lomwe limagwiritsidwa ntchito posungira magetsi. Amakhala ndi mbale ziwiri zachitsulo zomwe zimayikidwa pafupi ndi zinthu zopanda conductive (zotchedwa dielectric) pakati.

Mphamvu yamagetsi ikadutsa pa capacitor, imayendetsa mbale. Mphamvu zamagetsi zosungidwazi zitha kugwiritsidwa ntchito kupangira zida zamagetsi.

Ma capacitor amagwiritsidwa ntchito pazinthu zosiyanasiyana zamagetsi, kuphatikizapo makompyuta, mafoni am'manja, ndi mawailesi.

Pali mitundu iwiri ikuluikulu ya ma capacitor:

Polar Capacitors

Polarized capacitors ndi mtundu wa electrolytic capacitors omwe amagwiritsa ntchito electrolyte kuti apereke njira ya ma elekitironi. Mtundu uwu wa capacitor umagwiritsidwa ntchito pazinthu zosiyanasiyana kuphatikizapo magetsi, mauthenga, kulumikiza, ndi kusefa.

Electrolytic capacitors nthawi zambiri amakhala akuluakulu ndipo amakhala ndi mphamvu zambiri kuposa mitundu ina ya capacitor.

Non-polar capacitor

Non-polar capacitor ndi mtundu wa capacitor womwe umasunga mphamvu m'munda wamagetsi. Mtundu uwu wa capacitor ulibe polarizing electrode, kotero gawo lamagetsi ndilofanana.

Non-polar capacitor amagwiritsidwa ntchito pazida zosiyanasiyana, kuphatikiza mawailesi, ma TV, ndi zida zina zamagetsi.

Kodi ma capacitor terminals ndi chiyani?

Capacitor ili ndi ma terminals awiri: terminal yabwino ndi negative terminal. Malo abwino nthawi zambiri amalembedwa ndi chizindikiro "+", ndipo chopanda pake chimakhala ndi "-".

Ma terminals adapangidwa kuti azilumikiza capacitor kudera lamagetsi. Malo abwino amalumikizidwa ndi magetsi ndipo cholumikizira choyipa chimalumikizidwa pansi.

Momwe mungawerenge capacitor?

Kuti muwerenge capacitor, muyenera kudziwa zinthu ziwiri: voteji ndi capacitance.

Voltage ndi kuchuluka kwa mphamvu zamagetsi zomwe zimatha kusiyana pakati pa zabwino ndi zoipa za capacitor. Capacitance ndi kuthekera kwa capacitor kusunga ndalama zamagetsi.

Mphamvu yamagetsi nthawi zambiri imalembedwa pa capacitor, pamene capacitance nthawi zambiri imalembedwa pambali ya capacitor.

Chizindikiro cha Microfarad pa multimeter

Chizindikiro cha microfarads ndi "uF", chomwe mudzapeza pa kuyimba kwa multimeter yanu. Mutha kuziwonanso zitalembedwa ngati "uF". Kuti muyese ma microfarad, ikani multimeter kukhala "uF" kapena "uF".

Gawo lokhazikika la capacitance ndi farad (F). Microfarad ndi gawo limodzi mwa magawo miliyoni a farad (0.000001 F).

Microfarad (µF) imagwiritsidwa ntchito kuyeza kuchuluka kwa gawo lamagetsi kapena dera. Kuthekera kwa gawo lamagetsi kapena dera ndikutha kusunga ndalama zamagetsi.

Malingaliro oyambira pagawo la Farad

Farad ndi gawo la muyeso wa capacitance. Amatchedwa dzina la katswiri wa sayansi ya ku England Michael Faraday. A farad amayesa kuchuluka kwa magetsi omwe amasungidwa pa capacitor.

Pa tebulo mutha kuwona magawo osiyanasiyana a farad, komanso kuchuluka kwawo.

dzina	khalidwe	Kusintha	chitsanzo
mu picofa	pF	1pF = 10-12F	C=10 pF
нФ	nF	1 nf = 10-9F	C=10 nF
mu microwave	uF	1 uf = 10-6F	C=10uF
millifarad	mF	1 mf = 10-3F	C = 10 mF
farada	F	S=10F
kilofarad	kF	1kF=103F	C=10kF
megatariffs	MF	1MF=106F	S=10MF

Makhalidwe a luso mu farads

Kodi mungayese bwanji microfarad?

Kuti muyese mphamvu ya capacitor, mudzafunika multimeter yomwe imatha kuyeza ma microfarad. Ma multimeter ambiri otsika mtengo alibe izi.

Musanayambe kuyeza, onetsetsani kuti mwatulutsa capacitor kuti musawononge multimeter.

Choyamba zindikirani ma terminals abwino ndi oyipa a capacitor. Pa polarized capacitor, imodzi mwa ma terminals idzalembedwa "+" (zabwino) ndi ina "-" (zoyipa).

Kenako gwirizanitsani ma multimeter otsogolera ku ma capacitor terminals. Onetsetsani kuti kafukufuku wakuda walumikizidwa ku terminal yoyipa ndipo kafukufuku wofiyira walumikizidwa ku terminal yabwino.

Tsopano yatsani ma multimeter anu ndikuyiyika kuti ayeze ma microfarad (uF). Mudzawona kuwerenga mu ma microfarad pachiwonetsero.

Tsopano popeza mukudziwa kuti chizindikiro cha microfarad ndi chiyani komanso momwe mungayesere, mutha kuyamba kuzigwiritsa ntchito pama projekiti anu amagetsi.

Malangizo Otetezeka Poyesa Ma Capacitors

Kuyeza ma capacitors kumafuna kusamala.

Mosamala komanso moganiziratu, mutha kuyeza ma capacitor osawononga chipangizo chomwe chimadziyesa nokha.

• Valani magolovesi okhuthala kuti muteteze manja anu.
• Ngati capacitor ikanikizidwa motsutsana ndi thupi lanu (mwachitsanzo, poyiyeza kumbuyo kwa amplifier kapena malo ena olimba), imani pamtunda wouma, wotsekedwa (monga mphira wa rabara) kuti mupewe kugwedezeka kwa magetsi.
• Gwiritsani ntchito voltmeter yolondola, yoyendetsedwa bwino pamlingo woyenera. Osagwiritsa ntchito analogi voltmeter (moving pointer) yomwe ingawonongeke ndi mafunde apamwamba poyesa ma capacitor.
• Ngati simukutsimikiza ngati capacitor ndi polarized (ali ndi + ndi - terminals), yang'anani deta yake. Ngati deta ikusowa, ganizirani kuti ndi polarized.
• Osalumikiza capacitor molunjika ku malo opangira magetsi chifukwa izi zitha kuwononga capacitor.
• Mukamayesa magetsi a DC pa capacitor, dziwani kuti voltmeter yokha idzakhudza kuwerenga. Kuti muwerenge molondola, yezani voteji ndi mawaya ofupikitsidwa, ndiyeno chotsani voteji "yokondera" pakuwerenga ndi mawaya a mita olumikizidwa ndi capacitor.

Pomaliza

Tsopano popeza mukudziwa momwe chizindikiro cha microfarad chikuwoneka, mutha kuyeza capacitor ndi multimeter ya digito. Tikukhulupirira kuti bukhuli lakuthandizani kumvetsetsa momwe farads imagwirira ntchito ngati gawo loyezera.
