Uxhumano uchungechunge capacitors njengenhlangano capacitance Ukukhetha inketho

Epholisayo - wezinto umsakazo evame kakhulu, okuyinto itholakala kuyo yonke imiqondo. Siqukethe babashayeli amabili ahlukaniswe Kwe-dielectric Heating (kuye ngokuthi uhlobo capacitors wasebenzisa izinhlobo zayo ezihlukahlukene), isb ngokwenyama lesi sifunda, kodwa icala kungenziwa zanqwabelana Kwe-dielectric Heating. Isici esiyinhloko kwanoma iyiphi capacitor yikhono ukugcina icala - capacitance kanye voltage ezingu icala ngogesi. I capacitors electrolytic babe polarities, futhi elinesimo obunamandla futhi anhlobonhlobo voltages, iphepha ukumelana ukucindezeleka okukhulu, kodwa abe umthamo encane. Kukhona futhi amadivayisi nge umthamo obuhlukahlukene, kodwa uhlobo ngalunye - uhlelo lwayo lokusebenza.

Ngokuvamile hams abhekene nenkinga ukukhethwa capacitors ka capacitance noma voltage. Professionals ukwazi: ngokungabi bikho ilungelo, ungakwazi ukuqoqa inhlanganisela zomculo ezimbalwa, kuhlanganise ibhethri. Ngo ibhethri kuhlanganiswe uvunyelwe, uxhumano kuqondane and chungechunge of capacitors.

Ixhuma amadivayisi parallel, kungenzeka ukuba sifinyelele ukwanda umthamo. Jikelele kulesi ibhethri kuyoba ulingana isamba sazo zonke capacitances (Ceq. = C1 + C2 + ...), lo voltage ku element ngayinye kuzolingana. Lokhu kusho ukuthi le voltage okungenani capacitor, e enkompolo we isicelo, esiphezulu lonke ibhethri.

Uchungechunge uxhumano capacitors elisetshenziswa icala lapho kuyadingeka ukwandisa voltage olungamelana zikagesi noma ukunciphisa umthamo wabo. Kulesi samuntu, izakhi axhunyiwe kanje: qala komunye umkhawulo nezinye, okusho "plus" a "lokususa" nezinye. Umthamo capacitor okulingana kulokhu ibalwa le ndlela elandelayo :. 1 / Ceq = 1 / C1 +1 / C2 + ... Kusukela yilo, ukuthi capacitors ezimbili Ceq = C1 * C2 / (C1 + C2), futhi ngakho-ke, amandla webhethri kuyoba esingaphansi amandla ubuncane, elisetshenziswa kuyo.

Capacitor yasebhange ngokuvamile inikeza kuhlanganiswe (okuxubile)
Xhuma. Ukuze abale capacitance sedivayisi okuzofakwa kuyo parallel osetshenziswayo futhi uchungechunge uxhumano capacitors, wesifunda ngobugebengu ku izigaba ke zilandelana ibalwa umthamo ngamunye wabo. Ngakho, kubalwa capacitance C12 = C1 + C2 ke Ceq = C12 * C3 / (C3 + C12).

Through ukusungulwa capacitor amabhange ne ukucupha ehlukene kanye namalungiselelo
uxhumano, ungakwazi sithathe kunoma yisiphi isikhundla kunoma voltage nesithakazelo. Uchungechunge uxhumano of capacitors, kanye kuhlanganiswe, elisetshenziswa abaningi ngomumo eyenziwe amateur izifunda. Kulesi simo kufanele inake yokuthi capacitor ngamunye has ipharamitha kubaluleke kakhulu ngabanye - wamanje ukuvuza, kungaba unbalance voltage ngokuqondene kuqondane and capacitance e chungechunge. Kubalulekile kakhulu ukukhetha edingekayo shunt ukumelana.

Lapho ukusebenza capacitors kanye electronics, ungakhohlwa mayelana imithetho yokuphepha komuntu siqu kanye usongo yokuthi umuntu abanjwe ugesi.
