I-RC Series Circuit, equkethe i-resistor ne-capacitor, isebenza njengengxenye eyisisekelo kuzo zombili izinhlelo eziyisisekelo nezithuthukile zohlelo lwe-elekthronikhi.Kuyasiza ukuqonda imigomo ebalulekile efana nokuphendula imvamisa, ukushintshwa kwesigaba, nokuhlunga kwesiginali, okudlala indima ebalulekile ekwakhiweni kwesifunda kanye nokusebenza kwesiginali.Lokhu kuhlola kufaka izisekelo zethiyori futhi kufinyelela ezincelweni ezingokoqobo ngokusebenzisa izivivinyo kanye nokumbumbuluzwa.Ngokuhlangana ngokomzimba umjikelezo noma ukumodela ngokwedijithali, abafundi bangabamba ngendlela ebonakalayo inqubo yokushaja kanye nemiphumela yengxenye v ariat ion, okwenza imiqondo eyinkimbinkimbi ifinyeleleke kalula futhi ikhumbuleke.

I-RC Circuit, emfushane yesekethe lokumelana-amandla, iyisisekelo kuma-elekthronikhi ezimpawu zokukhohlisa ngokumelana nama-capacitors.Lemibuthano yaziwa kakhulu ngekhono labo lokushintsha izigaba nezimpawu zokuhlunga, kusetshenziswa amalungiselelo alula ngalezi zinto.Isifunda esiyisisekelo se-RC, esivame ukubizwa ngokuthi isekethe se-RC yokuqala ye-RC, imvamisa kufaka phakathi nje ukumelana ne-capacitor eyodwa.

Ngokusetha okujwayelekile, i-voltage yokufaka isetshenziswa elungiselelweni lokunyusa le-resistor ne-capacitor.Ukukhishwa kungadonswa ngaphesheya kwe-resistor noma i-capacitor, ngakunye okunikeza izimpendulo ezihlukile kuma-frequency amanga ngenxa yezimpawu ezihlukile zeCapacitor.Lokhu kuguqulwa kuvumela amaseliphu e-RC ukwenza izindima ezahlukahlukene kumadivayisi kagesi, njengokuhlanganisa nokuhlunga amasiginali noma ukuguqula ama-waveforms lapho uvinjelwe ugesi wesinyathelo.

Isifunda se-RC singalungiswa ngezindlela eziningi - uchungechunge, ukufana, noma inhlanganisela yazo zombili, ezaziwa ngokuthi uchungechunge - ukufana.Ukucushwa ngakunye kuthinta imvamisa yesiginali ehlukile: Ukuxhumeka kochungechunge kuvame ukumisa imvamisa ephansi, ngenkathi ukuxhumana okufanayo kusetshenziselwa ukunciphisa amaza aphezulu.Lo mehluko ngokuyinhloko ngenxa yendlela yokumelana nama-capacitors axhumana ngayo nomjikelezo;Ukumelana ngqo nokuphikisana ngokuqondile ngenkathi ama-capacitors egcina futhi uyikhulule, inomthelela ekutheni umjikelezo uphendula kanjani kumafrikhwensi ahlukahlukene.

Ngokungafani nemibuthano ehlanganisa ama-Inductors, njengezindawo zokujikeleza ze-LC, amasekethe alula we-RC awakwazi ukuhlanganisa njengoba abashumayezayo abagcini amandla.Le mfanelo ithonya kahle ukuthi iziqebele ze-RC zisetshenziswa kanjani, zigxile emandleni azo zokuhlunga esikhundleni sokugcinwa kwamandla noma i-resonance.Ukucushwa ngakunye kusebenza inhloso ethile, okwenza amathuluzi we-RC Circuile ahlukahlukene ekutadisheni ngokomqondo kanye nesicelo esisebenzayo ekuklameni ngogesi.

I-RC Series Circuit, empeleni yakhiwa i-resistor (Um) ne-capacitor (C) Ngochungechunge, isebenza ngomgomo oqondile.Lapho ukushintshwa komjikelezo kuvaliwe, iCapacitor iqala ukushaja kusuka kumandla kagesi asetshenzisiwe (V), iqala ukugeleza kwamanje ngokusebenzisa umjikelezo.Njengoba i-capacitor ishajela, ukunyuka kancane kancane kancane kuze kube yilapho i-capacitor ifinyelela emandleni ayo, lapho iyeka ukwamukela inkokhiso, kanye nokuzinza kwamanje ngenani layo eliphakeme, kubalwa njenge .

Inqubo yokushaja ye-capacitor ingachazwa ngokwezibalo , lapho ngikhona okwamanje, V ugesi, Um Ingabe ukumelana, C I-capacitance, t isikhathi, futhi e isisekelo se-logarithm yemvelo.Le fomula ikhombisa ukuthi izinguquko zamanje ngokuhamba kwesikhathi njengezindleko zeCapacitor, ngomkhiqizo wamanani wokumelana kanye namanani (i-RC) echaza isikhathi esingesifunda, esibonisa ijubane elisha ngaso umjikelezo.

Ukukhishwa kwenzeka lapho kuvulwa inkinobho, kubuyisela emuva inqubo: Kukhishwe amandla agciniwe eCapacitor, okwenza ukuthi okwamanje kuqhume ngakolunye uhlangothi kuze kube yilapho i-capacitor ikhishwe.Lokhu kushaja kanye nomjikelezo wokukhipha umjikelezo kubalulekile kuzinhlelo zokusebenza ezinjengokuguqulwa kwesiginali, ukuhlunga, kanye nemisipha yesikhathi ngenxa yendlela yokuqagela lapho ushintsho lwamanje nogesi.

Ukuziphatha kochungechunge lwe-RC Series futhi kuyahlukahluka ngokuvama.Kumafrikhwensi aphansi, i-capacitor isebenza ngokulandela umjikelezo ovulekile, ukulimaza kakhulu ukuhamba kwamanje.Njengoba imvamisa inyuka, ukuphendula kwe-capacive kwehla, okwenza kube lula okwamanje kudlule.Lolu shintsho ekulweni nemvamisa luvumela umjikelezo wochungechunge lwe-RC ukuthi enze njengesihlungi, ukhetha ukunqoba imvamisa ngaphansi komkhawulo othile (imvamisa eshintshayo ).

Ngaphezu kwemisebenzi eqinile yombuso, amaseliphu e-RC nawo afundwa izimpendulo zawo zesikhashana uma eshintshwa ngokuzumayo kumandla kagesi, njengalapho ukunikezwa kwamandla kwe-DC kuvulwa noma kuvaliwe.Lesi simo sibizwa ngenqubo yesikhashana, lapho ukuguqulwa kwesifunda kusuka esimweni esisodwa esizinzile kuya kwesinye.Amandla wale nqubo ancike kakhulu esikhathini se-RC, esiphethe ukuthi isifunda sisheshe kanjani ukuguquka ngokushesha.

Ekugcineni, amaseketheriya we-RC Series asebenza imisebenzi eminingi kuzo zombili izinhlelo zokusebenza ze-DC kanye ne-AC, ukuphatha imisebenzi esukela ekubambezelweni kwezimpawu zokubambezela ukuhlanganisa noma ukuhlanganisa izinto ezahlukahlukene zesifunda.Lokhu kuguquguquka kwezinto eziguquguqukayo kusuka ekuxhumaneni okuyingqayizivele phakathi kwe-resistor ne-capacitor, ehlanganisa ukunquma impendulo ephelele yesifunda kuya ekuguqukeni kwamandla kagesi kanye nemvamisa.

Emjikelezweni wochungechunge lwe-RC, ukuxhumeka phakathi komphikisi (R) kanye ne-capacitor (C) Ithonya kokubili ukuhanjiswa kwamanje nokusatshalaliswa kwamandla.Indima eyinhloko yokumelana nokulawula ukuhamba kwamanje.Lobu budlelwano bunqunyelwe umthetho kaHomm, othi , lapho V ugesi futhi Mina okwamanje.Empeleni, izenzo zokuphikisana njengebhodlela, elawula ugesi ongakanani ongadlula kunoma yisiphi isikhathi.

Umsebenzi weCapacitor ucacile ngokwengeziwe njengoba kugcina okwesikhashana amandla kagesi bese kukhululeka emuva esifundeni.I-voltage iwela i-capacitor (I-VC) Izixhumanisi ngecala layo eligcinwe (Qhakaziza) futhi kubalwa kusetshenziswa ifomula .Lobu budlelwano buqokomisa umthamo weCapacitor ukubamba icala, umthelela ngokuqondile ama-voltage it bonisa.Ngesikhathi sokusebenza, amandla okushaja kanye nokukhipha i-capacitor kubalulekile ekuqondeni amasekethe we-RC.Isikhathi njalo (shushu), kuchazwe njenge , i-capacitor ifinyelela ngokushesha kangakanani cishe ama-63.2% kagesi ogcwele onikezwe ngumthombo (V₀).Lesi sikhathi sibonisa njalo ukuthi umjikelezo uvumelana kanjani nokufaka izinguquko, nezakhiwo ze-resistor ne-capacitor zichaza ijubane lalesi simo.

I-voltage i-capacitor kunoma yisiphi isikhathi esinikeziwe ngesikhathi sokukhokhiswa, ekhombisa ukwanda okungaqondile komugqa njengoba iCapacitor igcwaliswa.Le equation ichaza ukuthi izinga lokushaja libambeka kanjani njengoba i-capacitor isondela umthamo ophelele.

Ngakolunye uhlangothi, ngesikhathi sokuphuma, ivolumu yeCapacitor yehla ngokusho , ukuveza ukwehla okuqondile kwamandla agcinwe ngokuhamba kwesikhathi.Le nqubo ihlinzeka ngesithombe esicacile sokuthi ikhishwe kanjani eCaphaCitor ibuyele esifundeni.Kuzinhlelo zokusebenza ze-AC, umehluko wesigaba phakathi kwamandla kagesi nawamanje, Φ, iba nzima.Lo mehluko, ubalwa njengoba -phi ω Imelela imvamisa ye-angular, ikhombisa ukubambezeleka okubangelwa yi-capacitor, okuthinta isikhathi phakathi lapho kuhamba nama-voltage ushintsho ezingxenyeni.

Sekukonke, imikhawulo yokuphikisana futhi iqondise ukuhamba kwamanje ngenkathi i-capacitor igcina futhi iguqule i-voltage.Ngokubambisana, banquma izici zokuphendula kwabajikelezo, njengokuthi masinyane kangakanani kungakhokhisa futhi kukhiphe ngokushesha futhi nokushintsha kwesigaba okwenzeka ngokushintshana ngezimo zamanje.Lokhu kuhlalisa okuhlanganisiwe kunciphisa ukusebenza okuyisisekelo kwemibuthano yochungechunge lwe-RC, kubenza bahlanganiswe ezinhlelweni ezahlukahlukene ze-elekthronikhi.

Ukuqonda ukusebenza kwe-RC Series Circuit, kubalulekile ukuqala ngezibalo eziyisisekelo ezichaza impendulo yazo kuzinguquko ku-voltage yokufaka.Thatha ukuthi sinokushintsha kwamandla kagesi okuguqulwe okuvezwe njengoba I-VIN (T), ngamandla kagesi ngaphesheya kwelebula elibhalwe njenge Vr (t) nangaphesheya kweCapacitor njengoba Vc (t).Emjikelezweni ochungechungeni, okufanayo kwamanje, I (t) ugeleza ngokusebenzisa bobabili i-resistor ne-capacitor.

Ukufaka umthetho we-Kirchhoff's Voltage Law (KVL), okusho ukuthi i-voltage ephelele ezungeze noma iyiphi i-loop evaliwe esifundeni kufanele silingana ne-zero, sithola ukuthi i-voltage yokufaka ilingana nenani lamavolumu enqamula i-resistor ne-capacitor:

I-voltage ngaphesheya komphikisi ingabalwa kusetshenziswa umthetho we-ohm:

KwiCapacitor, iVoltage VC (T) ihlobene necala le-Q (T) liphethe, linikezwe ngu:

Njengoba okwamanje kuchazwa njengokugeleza kwezinga lokugeleza, sinakho:

Ngokufaka esikhundleni Q (t) ku-equation ye Vc (t), futhi usebenzisa okususelwa ekushayweni I (t), sithola i-equation ehlukile yokwehluka kwe-RC Series Circuit:

Ukubuyisa okunye Q (t) ngokuhlanganiswa kwe I (t), siyathola:

Okwamanje, i (t), ecubungula izinga lokushintshwa kwamandla kagesi kulo lonke elaseCapacitor, sisebenzisa:

Ukuhlanganisa bonke lobu budlelwano kusinikeza ukulingana okuhlukile okuchaza i-voltage kuyo yonke i-capacitor:

Lokhu kuyi-equation ehlukile yoku-oda eqondile ekhombisa ukuguqulwa kokuncika kwe-voltage kuyo yonke i-capacitor.Ukuxazulula le equation kusivumela ukuthi sichaze ngokunembile ukuthi i-capacitor voltage ivela kanjani.Lokhu kuqonda kubalulekile ekuhlaziyeni kokubili ukushaja kanye nokukhipha imijikelezo ye-capacitor, kanye nokusabela komjikelezo kumafrikhwensi ahlukahlukene.Le ndlela ebanzi ihlinzeka ngokuqonda okujulile ngezimpawu ezinamandla zochungechunge lwe-RC.

Ukubhala kabusha incazelo yochungechunge lwe-RC Series, okugxilwe ekuxhumaneni komuntu kanye nencazelo eqondile, eyenziwe lula, ake sithuthukise okuhlangenwe nakho okubonakalayo kanye nokusebenza okuqhubekayo okubandakanyekile ngenkathi sigcina umyalezo oyisisekelo nokuvumelana:

Ku-RC Series Circuit, i-resistor ne-capacitor isebenza nge-tandem ukulawula ukuhamba kukagesi, kubalulekile lapho usebenza ngokushintshana kwemisinga.Ukubulawa okuphelele komjikelezo, okumele , kuhlanganisa ukumelana r kanye ne-xc ephendula nge-capacitive.Isici esiyisihluthulelo salokhu kusetha ukuthi amanani okuvimbela kuzo zombili izakhi ziyehluka ngezinguquko zemvamisa.Njengoba imvamisa inyuka, ukungcola kwe-capacitor kuncipha, kuvumela okwengeziwe okwengeziwe ukuthi kudlule, ngenkathi ukumelana empeleni kuhlala kuhlale njalo.

Ukuphazamiseka, okubonisiwe njengoba Imidlalo futhi kulinganiswe kuma-ohms (ω), idlala indima ebalulekile ekunqumeni ukuthi umjikelezo uphendula kanjani lapho eshintsha khona.Njengesemibungu ye-RL Series, ukumelana Um kanye ne-capacitive ephendula x_C yefomu le-RC Circuit unxantathu olwaziwa ngokuthi unxantathu we-impedance.Lonxantathu uhlangana eduze nonxantathu wamandla kagesi, nangokusebenzisa i-Pythagorean Theorem, ungabala ukuqubuka ngokuphelele kwesekethe.

Uma kukhulunywa ngezicelo ezisebenzayo, cabanga ngamakhanda, asebenzisa lezi zimiso.Ama-headphone aphezulu okuvimbela, imvamisa edlula ama-ohms angama-200, asetshenziswa ngokujwayelekile ngamakhompyutha wedeskithophu, ama-amplifiers amandla, kanye nemishini yomsindo ochwepheshe.Lawa mamodeli aphezulu wokuvimbela ahambelana kahle namakhono okuphuma we-elekthronikhi yebanga lobuchwepheshe.Lapho usebenzisa la makhanda, kubalulekile ukulungisa ivolumu kancane kancane ukuze ugweme ukulayisha ngokweqile nokulimaza izinto zangaphakathi ezibucayi, njengekhoyili yezwi.

Ngakolunye uhlangothi, ama-headphones aphansi okuvimbela, imvamisa ngaphansi kwama-50 ohms, akhethelwa amadivaysi aphathekayo afana nabadlali be-CD, abadlali be-MD, noma abadlali be-MP3.Lawa ma-headphone adinga amandla amancane ukuletha umsindo osezingeni eliphakeme, ukuzenza elungele ukusetshenziswa kweselula.Kodwa-ke, futhi bafuna ukunakwa ngokucophelela emazingeni okuzwela ukuqinisekisa ukusebenza kahle futhi kuvikele ukulimala kwamahedfoni noma ukuzwa.

Ukuvunyelwa Ukujikeleza kochungechunge lwe-RC kukhulunywa kalula ngogesi, kubalwa njengokuphikisana kokungaphakathi ().Leli nani lihlanganisa konke ukumelana (Um) kanye nokuphendula (X) yesifunda.Ukumelana kuphikisana nokugeleza kwamanje ngokuguqula amandla kagesi ukushisa, kanti ukuphendula kugcina amandla okwesikhashana esisekelweni.

Qala ngokubhala i-Intedance , lapho ama-r amele khona ukumelana, X ukuphendula, futhi +bha iyunithi yokucabanga.Sebenzisa ifomula y = 1 / (Um +zela uhlobo).Lo msebenzi ufaka izinombolo eziyinkimbinkimbi futhi usinika .Lapha, Izithombe ukuhanjiswa (amandla okuhamba kwangempela wokugeleza kwamanje) futhi B Ingabe ukwethuka (amandla e-Cirli okusabela ezinguquko kumanje).

Lesi sibalo asivezi ukuthuthuka kwabajikelezi kuphela kepha futhi nezimpawu zayo zokuphendula ezinamandla, zibalulekile ukuhlaziya umjikelezo we-AC.Ukuziphatha nokuphangwa, kuthathwe ndawonye, ​​bonisa ukuthi umjikelezo udlula kanjani amanje nokuthi ugcina kanjani futhi ukhulula kanjani amandla.

Onjiniyela basebenzisa amanani wokuvumayo ukuthuthukisa ukwakheka kwesifunda, ikakhulukazi ezinhlazweni zemvamisa ephezulu efana nemijikelezo ye-radio frequency.Ukulungiswa kokuvumayo kusiza ekufaniseni kokufanisa, ukunciphisa ukuboniswa kwesiginali, futhi kuqinise ukusebenza kahle kokudlulisela.

Ngokutadisha impendulo yokuvumisa, onjiniyela bangahlola futhi babikezele ukusebenza kwesifunda ngaphansi kwezimo ezahlukahlukene njengokuphendula imvamisa, ukuqina nokuzwela.Hlomisa nge-Oscilloscope kanye ne-generator yesiginali ukukala i-voltage ye-Circuit futhi yamanje emafrikhweni ahlukahlukene.Gxila ikakhulukazi ku-cutoff frequency ukuhlola izibikezelo zethiyori bese uziqinisekisa ngokumelene nokubukwa okusebenzayo.Ngemibuthano ye-AC, qala ngokunquma ukuphendula (i-XC) ye-capacitor nge , lapho e f imvamisa yesiginali.Khomba ukubulawa okuphelele bese uyavuma .

Hlaziya umehluko wesigaba usebenzisa ukuqonda ukuguqulwa kwe-Signal Shape ukuguqulwa.Hlola ukuthi umjikelezo uphatha kanjani amaza ahlukile, ikakhulukazi aphawula isimilo esivamisile e-cutoff , lapho umjikelezo ushiya khona ekudluliseleni amasiginali.Ukuhlola ukuthi umehluko nomehluko wesigaba uhluka kanjani ngokuvama, kubalulekile ukuklama izihlungi ezisebenzayo kanye nama-processos wesiginali.Xoxa ngokuthi ukufundwa imvamisa, amashifu wesigaba, kanye ne-attenuation yesiginali ngenxa yezindawo zokujikeleza zithinta izinhlelo zokusebenza ezisebenzayo njengokuhlunga nokuhlunga nge-elekthronikhi.

Le ndlela iqeda izinqubo zokusebenza zibe yizinyathelo ezilawulekayo, zicebise ukuqonda komsebenzisi ngokuqonda okusebenzayo ekusingatheni kanye nokuhlaziya izifunda zochungechunge lwe-RC.

Emjikelezweni wochungechunge lwe-RC, zonke izinto zabelana njengamanje ezifanayo ngenxa yokucushwa kwazo kochungechunge.Le app yezenzo ezifanayo njengamanje njengezisekelo zomdwebo wethu we-phasor, esiza ngeso lengqondo ubudlelwano phakathi kwama-voltages ahlukene nemisinga ejikelezweni.Ake siqoke lokhu kwamanje Mina Njengesethenjwa Phansi, sibekwe ngeziqu ze-zero ku-DIAGRAM.Emgqonyeni, okwamanje Mina isethwe ngokuqondile kwesokudla, ukusungula umugqa wesethenjwa we-zero-degree.Amandla kagesi ngaphesheya kwe-Resistor (U_Um) Kusesigabeni nalokho okwenzeka kwamanje ngoba abamelana nanoma yisiphi isigaba sokushintsha.Ngakho-ke, U_Um idonswa njenge-veter evundlile ngendlela efanayo Mina, ukunwetshwa kusuka emthonjeni.

Ngokuphambene nalokho, i-voltage e-capacitor (U_C) kuholela ekhokhwa ngamanani ngama-degree angama-90 ngenxa yempahla ye-capacitive yokubambezela isigaba samanje.Leli voltage limelelwa yi-vector eqonde mpo ekhomba phezulu, kusukela esicebeni se U_Um vector.I-voltage ephelele U Esisekelweni yisamba se-vector U Amarandi U_C.Le mali yakha unxantathu ofanele nge U_Um na- U_C njengezinhlangothi eziseduze nezinhlangothi eziphambene, ngokulandelana.I-hypotenuse yalolu ntathu, isuka esuka kwimvelaphi iya kwisicoco se U_C vector, umele U.

I-sinusoidal yamanje ngokusebenzisa umjikelezo inikezwa ngesono (ωw), lapho i-Im iyi-amplitude ephezulu yamanje futhi ω imvamisa ye-angular.Ngenxa yalokho, ivolula elikuwo wonke umphikisi , zibukisa i-waveform yamanje.I-voltage kuyo yonke i-capacitor inikezwe ngu , ekhombisa ukushintshwa kwesigaba kwe--90 ° (noma ama-90 degrees ngaphambi kwale okwamanje).Unxantathu welungelo lomdwebo we-phasor ucacisa lokho ayigcini nje ngobukhulu kodwa futhi ebudlelwaneni besigaba, nge-voltage voltage veter (U) Ukuqeda unxantathu.

Ukuvikelwa ku-Series RC Circuit, okumelelwa njenge Imidlalo, kuhlanganisa ukumelana (Um) kanye nomphumela osebenzayo we-capacitance ngenani elilodwa elihlukahluka ngokuvama kwesiginali.Kuvezwa ngokwezibalo njengoba , lapho ω imvamisa ye-angular futhi C i-capacitance.Lapha, Um kwakha ingxenye yangempela yalowo obekuvikeleke, futhi imele ingxenye ethile, ekhombisa ukuthi i-capacitor ithonya kanjani umjikelezo.

Indlela yokushintshana kwendlela enokushintshana ngokufiphala yi-Pivotal yokusebenzisa amaseliphu e-CECICE RC kuzicelo zokuhlunga.Emathendeni aphansi, umjikelezo wesifunda ukhombisa ukungavikeleki okuphezulu, ukuvimba ngempumelelo la mafrikhwensi.Ngakolunye uhlangothi, ngamafrikhwensi aphezulu, amaconsi okulimaza, avumela la mafrikhwensi adlule ngokukhululeka.Lokhu kuziphatha kwenza amasekethe we-cheries RC alungele imisebenzi efana nokuhlunga umsindo ophansi ongafuneki noma ukuhambisa amasiginali afudumele aphezulu.

Ukusuka ekuhlungeleni imvamisa engafuneki ekubumbeni izimpendulo zesiginali, i-RC Series Circuit iyinhlangano ehlukahlukene yemisebenzi ye-elekthronikhi.Ngokuqonda izimiso eziyisisekelo ezinjengokuvinjelwa, ubudlelwano be-Phasor, kanye nokuziphatha okuthe xaxa kwale mibuthano, onjiniyela kanye nabaqambi bahlome izixazululo zobuciko ezilawula ukuthembeka kwesiginali ngezinhlelo eziyinkimbinkimbi ze-elekthronikhi.Ukuhlolwa okuningiliziwe kwale mibuthano, esekelwa ukuhlaziya kwezibalo kanye nezethulo ezibonakalayo ezinjengezethulo ze-Phasor, zinikeza ukuqonda okuphelele okubalulekile kunoma ngubani ofuna ukujulisa ukuqonda kwabo ama-electronic ama-electronic noma ukuthuthukisa amakhono abo asebenzayo ekuklameni kwesifunda nasekuxazululeni.

Umgomo we-RC (Resistor-Capacitor) umjikelezo uzungeza ukushaja kanye nokukhipha izinqubo ze-capacitor ngokusebenzisa i-resistor.Kulesi sifunda, amandla weCapacitor okugcina nokukhipha amandla kagesi axhumana nalowo msakazo, olawula izinga lapho ama-capacitor ekhoshwa noma alahlekelwe.

Emjikelezweni we-RC, okuholela kwamanje i-voltage kuyo yonke i-capacitor ngoba i-capacitor idinga ukuqala ukushaja ngaphambi kokuba i-voltage yayo ingavuka.Njengoba ukugeleza kwamanje ku-capacitor ukukukhokhisa, iziqongo zamanje ngaphambi kokuthi i-capacitor ifinyelela phezulu.Lo mphumela ubangela ukuhamba kwesigaba lapho isigaba samanje siholela khona isigaba se-voltage ngamadigri angama-90, ngokuya ngokuvama kwesiginali yokufaka.

Ukushintshwa kwamandla kagesi ku-RC Circuit ngesikhathi sokushaja kuchazwa ngumsebenzi we-exponential.Lapho kufakwa i-voltage, i-voltage kuyo yonke i-capactor ekuqaleni inyuka ngokushesha, bese yembulala njengoba isondela kuvoti lokuhlinzekwa.Ngokwezibalo, lokhu kuvezwa njenge , lapho V_C(t) Ingabe i-voltage voltage kuyo yonke i-capacitor ngesikhathi t, v0 voltage voltage, futhi i-rc isikhathi esihlala njalo isekethe, inqume ukuthi i-capacitor isebenza ngokushesha kangakanani.Ngakolunye uhlangothi, ngesikhathi sokudilizwa, i-voltage kuyo yonke i-capacitor inciphisa i-exponential, kulandela i-equation .
