Chii chiratidzo che microfarads pane multimeter?

Kana iwe uri mugadziri wemagetsi kana kuti uchangotanga nemagetsi, unofanirwa kuziva nezvemhando dzakasiyana dzemagetsi. Imwe yeiyi ndiyo microfarad.

So Chii chiratidzo che microfarads pane multimeter?? Ngatipindure mubvunzo uyu.

Ndekupi kwatinoshandisa microfarads?

Microfarad inoshandiswa mumhando dzakasiyana dzemidziyo yemagetsi, kusanganisira capacitors, transistors, uye maseketi akabatanidzwa.

Asi kazhinji iwe uchasangana navo pakuyera capacitance ye capacitor.

Chii chinonzi capacitor?

A capacitor chinhu chemagetsi chinoshandiswa kuchengetedza chaji yemagetsi. Iyo ine mahwendefa maviri esimbi akaiswa padhuze neasina-conductive zvinhu (anonzi dielectric) pakati.

Kana simba remagetsi richipfuura nepakati pe capacitor, rinobhadhara mahwendefa. Iri simba remagetsi rakachengetwa rinobva rashandiswa kusimbisa midziyo yemagetsi.

Macapacitor anoshandiswa mumhando dzakasiyana dzemidziyo yemagetsi, kusanganisira makomputa, nharembozha, uye maredhiyo.

Kune maviri makuru marudzi e capacitor:

Polar Capacitors

Polar capacitors imhando ye electrolytic capacitor inoshandisa electrolyte kupa nzira yemagetsi. Iyi mhando ye capacitor inoshandiswa mumhando dzakasiyana dzekushandisa dzinosanganisira magetsi emagetsi, kutaurirana, kubvisa, uye kusefa.

Electrolytic capacitors inowanzova yakakura uye ine hukuru hwepamusoro kupfuura mamwe marudzi e-capacitors.

Non-polar capacitor

Non-polar capacitors imhando ye capacitor inochengetedza simba mumunda wemagetsi. Iyi mhando ye capacitor haina polarizing electrode, saka munda wemagetsi unoenzana.

Non-polar capacitors anoshandiswa mumhando dzakasiyana-siyana, kusanganisira maredhiyo, terevhizheni, uye zvimwe zvigadzirwa zvemagetsi.

Chii chinonzi capacitor terminals?

A capacitor ine materminals maviri: positive terminal uye negative terminal. Positive terminal inowanzoiswa chiratidzo "+", uye inegetive terminal ine "-" chiratidzo.

Iwo materminals akagadzirirwa kubatanidza capacitor kudunhu remagetsi. Iyo yakanaka terminal yakabatana kune magetsi uye iyo isina kunaka terminal yakabatana pasi.

Nzira yekuverenga sei capacitor?

Kuti uverenge capacitor, unofanirwa kuziva zvinhu zviviri: voltage uye capacitance.

Voltage ndiyo huwandu hwemagetsi anogona mutsauko pakati peiyo yakanaka uye yakaipa terminals ye capacitor. Capacitance ndiko kukwanisa kwe capacitor kuchengetedza magetsi emagetsi.

Voltage inowanzonyorwa pane capacitor, nepo capacitance inowanzonyorwa padivi recapacitor.

Microfarad chiratidzo pane multimeter

Chiratidzo che microfarads i "uF", iyo yauchawana pane dial ye multimeter yako. Iwe unogona zvakare kuiona yakanyorwa se "uF". Kuyera mu microfarads, isa iyo multimeter kune "uF" kana "uF" chinzvimbo.

Iyo yakajairwa unit ye ​​capacitance ndeye farad (F). A microfarad inosvika miriyoni imwe yefarad (0.000001 F).

A microfarad (µF) inoshandiswa kuyera capacitance yechikamu chemagetsi kana dunhu. Iyo capacitance yechikamu chemagetsi kana dunhu ndiko kugona kuchengetedza mutero wemagetsi.

Mafungiro ekutanga nezveFarad unit

Faradhi chikamu chechiyero che capacitance. Inotumidzwa zita remuChirungu wefizikisi Michael Faraday. A farad inoyera kuti yakawanda sei magetsi inochengeterwa pane capacitor.

Mutafura iwe unogona kuona zvikamu zvakasiyana-siyana zvefarad, pamwe chete nekuenzana kwavo.

zita	chiratidzo	Shanduko	muenzaniso
mu picofara	pF	1pF = 10-12F	C=10 pF
нФ	nF	1 nF = 10-9F	C=10 nF
mu microwave	uF	1 µF = 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

Capacitance kukosha mune farads

Nzira yekuyera sei microfarad?

Kuti uedze capacitance ye capacitor, iwe uchada multimeter inokwanisa kuyera microfarads. Mazhinji akachipa multimeter haana chimiro ichi.

Usati wayera, iva nechokwadi chekusunungura capacitor kuitira kuti usakuvadza multimeter.

Kutanga tsvaga iyo yakanaka uye yakaipa terminals ye capacitor. Pane polarized capacitor, imwe yematerminal ichaiswa "+" (positive) uye imwe "-" (negative).

Wobva wabatanidza iyo multimeter inotungamira kune capacitor terminals. Ita shuwa kuti iyo nhema probe yakabatana kune iyo yakaipa terminal uye iyo tsvuku probe yakabatana kune yakanaka terminal.

Iye zvino vhura multimeter yako uye uiise kuyera microfarads (uF). Iwe uchaona kuverenga mu microfarads pachiratidziro.

Iye zvino zvaunoziva kuti chiratidzo che microfarad chii uye kuti ungazviyera sei, unogona kutanga kuzvishandisa mumapurojekiti ako emagetsi.

Mazano Ekuchengetedza Paunenge Uchiedza Capacitors

Kuyera capacitors kunoda dzimwe dziviriro.

Nekutarisira uye kufanofunga, unogona kuyera capacitors pasina kukuvadza mudziyo unoyera iwo kana iwe pachako.

• Pfeka magirovhosi akakora kudzivirira maoko ako.
• Kana iyo capacitor ichimanikidzwa kurwisa muviri wako (somuenzaniso, paunenge uchiyera kumashure kweamplifier kana imwe nzvimbo yakaoma), mira panzvimbo yakaoma, yakavharidzirwa (yakadai serubha mat) kuti udzivise kushamiswa kwemagetsi.
• Shandisa chaiyo, yakanyatso calibrated dijitari voltmeter seti kune iyo chaiyo renji. Usashandise analog voltmeter (inofambisa pointer) inogona kukuvadzwa nemhepo yakakwira paunenge uchiyedza capacitors.
• Kana iwe usina chokwadi kana capacitor iri polarized (ine + uye - zviteshi), tarisa database yayo. Kana iyo database isipo, fungidzira kuti yakaitwa polarized.
• Usabatanidza capacitor zvakananga kune magetsi ekugadzirisa magetsi sezvo izvi zvinogona kukuvadza capacitor.
• Pakuyera DC voltage pane capacitor, ziva kuti voltmeter pachayo ichakanganisa kuverenga. Kuti uwane kuverenga kwakaringana, tanga wayera voltage newaya dzemamita dzakapfupikiswa, wobva wabvisa voltage "yakarerekera" kubva pakuverenga newaya dzemamita dzakabatanidzwa kune capacitor.

mhedziso

Iye zvino zvaunoziva kuti chiratidzo che microfarad chinoratidzika sei, unogona kungoyera capacitor ne digital multimeter. Tinovimba kuti gwara iri rakubatsira kuti unzwisise kuti farads inoshanda sei sechikamu chekuyera.
