Letšoao la microfarad ho multimeter ke eng?
Tse ka hare
Haeba u le ramotlakase kapa u sa tsoa qala ka motlakase, u lokela ho ela hloko likarolo tse fapaneng tsa motlakase. E 'ngoe ea tsona ke microfarad.
So Letšoao la microfarad ho multimeter ke eng?? Ha re arabeng potso ena.
Re sebelisa li-microfarads hokae?
Li-microfarad li sebelisoa mefuteng e mengata ea lisebelisoa tsa elektroniki, ho kenyeletsoa li-capacitor, transistors le li-circuits tse kopaneng.
Empa hangata u tla kopana le bona ha u lekanya bokhoni ba capacitor.
Capacitor ke eng?
Capacitor ke karolo ea elektronike e sebelisoang ho boloka tefiso ea motlakase. E na le lipoleiti tse peli tsa tšepe tse behiloeng haufi le thepa e sa sebetseng (e bitsoang dielectric) lipakeng.
Ha motlakase o feta ka capacitor, o lefella lipoleiti. Joale matla ana a bolokiloeng a motlakase a ka sebelisoa ho matlafatsa lisebelisoa tsa elektroniki.
Li-capacitor li sebelisoa mefuteng e mengata ea lisebelisoa tsa elektroniki, ho kenyelletsa likhomphutha, mehala ea cellular le liea-le-moea.
Ho na le mefuta e 'meli e meholo ea li-capacitor:
Polar Capacitors
Polarized capacitor ke mofuta oa electrolytic capacitor e sebelisang electrolyte ho fana ka tsela bakeng sa lielektrone. Mofuta ona oa capacitor o sebelisoa lits'ebetsong tse fapaneng ho kenyelletsa phepelo ea motlakase, likhokahano, ho kopanya le ho sefa.
Li-electrolytic capacitor hangata li kholo ebile li na le matla a holimo ho feta mefuta e meng ea li-capacitor.
Non-polar capacitor
Li-non-polar capacitor ke mofuta oa capacitor o bolokang matla sebakeng sa motlakase. Mofuta ona oa capacitor ha o na electrode ea polarizing, kahoo sebaka sa motlakase se na le symmetrical.
Li-non-polar capacitor li sebelisoa lisebelisoa tse fapaneng, ho kenyelletsa le liea-le-moea, lithelevishene le lisebelisoa tse ling tsa elektroniki.
Li-terminals tsa capacitor ke eng?
Capacitor e na le li-terminals tse peli: terminal e ntle le e mpe. Theminale e nepahetseng hangata e tšoauoa ka lets'oao la "+", 'me lets'oao le nang le "-".
Li-terminals li etselitsoe ho hokahanya capacitor ho potoloho ea motlakase. Theminale e ntle e hoketsoe ho phepelo ea motlakase 'me terminal e mpe e hoketsoe fatše.
Mokhoa oa ho bala capacitor?
Ho bala capacitor, o hloka ho tseba lintho tse peli: voltage le capacitance.
Voltage ke palo ea phapang ea matla a motlakase lipakeng tsa li-terminals tse ntle le tse mpe tsa capacitor. Capacitance ke bokhoni ba capacitor ho boloka tefiso ea motlakase.
Hangata motlakase o ngoloa ho capacitor, ha capacitance e atisa ho ngoloa ka lehlakoreng la capacitor.
Letšoao la microfarad ho multimeter
Letšoao la microfarads ke "uF", eo u tla e fumana ho daela ea multimeter ea hau. U ka boela ua bona e ngotsoe e le "uF". Ho lekanya ka microfarads, beha multimeter sebakeng sa "uF" kapa "uF".
Yuniti e tloaelehileng ea matla ke farad (F). Microfarad ke karolo ea milione ea farad (0.000001 F).
Microfarad (µF) e sebelisetsoa ho lekanya bokhoni ba motsoako oa motlakase kapa potoloho. Bokhoni ba karolo ea motlakase kapa potoloho ke bokhoni ba ho boloka tefiso ea motlakase.
Likhopolo tsa mantlha mabapi le yuniti ea Farad
Farad ke tekanyo ea tekanyo bakeng sa bokhoni. E rehelletsoe ka setsebi sa fisiks sa Lenyesemane Michael Faraday. A farad e lekanya hore na tefiso ea motlakase e kae e bolokiloe ka capacitor.
Ka tafoleng u ka bona lihlopha tse fapaneng tsa farad, hammoho le boholo ba tsona.

Mokhoa oa ho lekanya microfarad?
Ho lekola bokhoni ba capacitor, o tla hloka multimeter e khonang ho lekanya li-microfarads. Li-multimeter tse ngata tse theko e tlaase ha li na tšobotsi ena.
Pele u lekanya, etsa bonnete ba hore u ntša capacitor e le hore u se ke ua senya multimeter.
Ntlha ea pele, khetholla li-terminals tse ntle le tse mpe tsa capacitor. Ho polarized capacitor, e 'ngoe ea li-terminals e tla tšoauoa "+" (positive) le e' ngoe "-" (e mpe).
Ebe o kopanya multimeter e lebisa ho li-terminals tsa capacitor. Etsa bonnete ba hore probe e ntšo e hoketsoe ho theminale e fosahetseng 'me probe e khubelu e hokahane le terminal e nepahetseng.
Joale bulela multimeter ea hau 'me u e behe ho lekanya li-microfarads (uF). U tla bona ho bala ka microfarads skrineng.
Kaha joale u tseba hore na letšoao la microfarad ke eng le hore na u ka li lekanya joang, u ka qala ho li sebelisa mererong ea hau ea motlakase.
Litlhahiso tsa Tšireletseho Ha U Leka Li-Capacitors
Ho lekanya li-capacitor ho hloka litemoso tse itseng.
Ka tlhokomelo le ho nahana esale pele, o ka lekanya li-capacitor ntle le ho senya sesebelisoa se lekanyang bona kapa uena.
- Apara liatlana tse teteaneng ho sireletsa matsoho a hau.
- Haeba capacitor e hatelloa khahlanong le 'mele oa hau (mohlala, ha u e lekanya ka morao ho amplifier kapa sebaka se seng se thata), ema holim'a sebaka se omileng, se sirelelitsoeng (joaloka 'mete oa rabara) ho qoba ho tsosoa ke motlakase.
- Sebelisa voltmeter ea dijithale e nepahetseng, e lekantsoeng hantle ho isa boemong bo nepahetseng. U se ke ua sebelisa analog voltmeter (pointer pointer) e ka 'nang ea senngoa ke maqhubu a phahameng ha u hlahloba li-capacitor.
- Haeba o sa tsebe hantle hore na capacitor e polarized (e na le + le - terminals), hlahloba database ea eona. Haeba database e le sieo, nka hore e polarized.
- Se ke oa hokela capacitor ka kotloloho ho li-terminals tsa phepelo ea motlakase kaha sena se ka senya capacitor.
- Ha u lekanya motlakase oa DC ho feta capacitor, hlokomela hore voltmeter ka boeona e tla ama ho bala. Ho fumana 'malo o nepahetseng, pele lekanya matla a motlakase ka methareng e khutšoanyane, ebe o tlosa "voltage" ena ho tloha ho bala ka methareng e amanang le capacitor.
fihlela qeto e
Kaha joale u tseba hore na letšoao la microfarad le shebahala joang, u ka khona ho lekanya capacitor ka multimeter ea digital. Re tšepa hore tataiso ena e u thusitse ho utloisisa hore na farads e sebetsa joang e le tekanyo ea tekanyo.
