Capacitance korontada ee capacitor ah: dabeecadda iyo sifooyinka ugu muhiimsan ee

Labada in industry iyo nolol maalmeedka inta badan u baahan tahay abuurista tiro badan oo togan iyo kuwa taban eedeeyay korontada. Waxaa cad in la electrification ee jidhkooda iyo induction ku electrostatic in la sameeyo wax aan macquul ahayn. Waxaa muuqato in aad u baahan tahay qalab gaar ah. qalab noocan oo kale ah waxay u adeegtaa sida condenser ah.

capacitor waa nidaam sahlan oo kooban dielectric ee kala ah laba birood. Waa arrin aad u muhiim ah in dhumucda insulator ahaa yar marka la barbar dhigo xajmiga oo ka mid ah taarikada isla, kirishbooyada ie.

Foomka ugu fudud ee qalabka korontada capacitive waa capacitor guri, taas oo adag oo ah ka mid ah laba birood biraha kala dielectric ah. Haddii taarikada, kuwaas oo qaadan hadda korontada, qiimaha taranta xiisadda ka timi u dhaxaysa duurka oo korontada ah waa ku dhowaad laba jeer ka badan xoogga la mid ah ka mid ah, kuwaas oo tumeen.

The tilmaame ugu muhiimsan ee nidaamka this waa capacitance korontada. capacitance korontada ee capacitor marka loo eego saldhigyada electro uyeelaysaan kuwo saamiga la'aan mid ka mid ah taarikada si danab ka codsatay dhexeeya kirishbooyada qalab this. Guud ahaan, capacitance koronto ee capacitor waa sida soo socota:

C = q / U

Haddii booska uu ka taarikada ee meel isma badelin waqti dheer, capacitance koronto ee capacitor weli joogto ah (iyadoon loo eegayn amarka taranta on taarikada ah).

In System Caalamiga ah ee cabirka jirka ee capacitance korontada ee capacitor la qiyaasay in farads (F). Sida laga soo xigtay soocidda this, mid ka mid farad tilmaamay capacitance korontada ee qalabka sida, taas oo danab u dhexeeya insulators waa mid ka mid volt a, iyo caddadka lacag taas waxaa laga codsadaa in saxanka, waa loo siman yahay si ay mid la surto.

Dhab ahaantii, mid farad - taasi waa qiimaha aad u weyn, sidaas oo kale ayaa inta badan la isticmaalo unugyada sida microfarad ah, iyo xataa Nanofarad PF.

capacitance Flat korontada ee capacitor ku xirnaan doontaa degaanka ee electrodes iyo la kordhin doonaa iyadoo yaraynta masaafada u dhexeeya iyaga. Si aad si weyn u kordhiyo awoodda korontada ee qalabka la soo bandhigo dhexeeya kirishbooyada ama dielectric kale.

Xaaladaha intooda badan, electrodes ee capacitors ka-bireed khafiif ah oo goomahooda sida muhiimka ah loo isticmaalo a waraaqaha, Miikaa ama dhoobada sameeyey. Waa waafaqsan wax u adeegaya sida saldhig u ah dielectrics, capacitors, oo aan magacooda hesho - warqad, dhoobada, hawada, Miikaa. Si cadaalad ah baahsan sannadihii la soo dhaafay helay capacitors ku electrolytic in ku filan yihiin dhinacyada is haysta waxay leeyihiin awoodda korontada badan. Sababtoo ah ay sifooyinkaasi, waxay hubkaas ayaa loo isticmaalaa in qalabka guriga, iyo sidoo kale rectifier hadda ah.

Capacitors waa mid ka mid ah qalabka korontada ugu muhiim ah, iyada oo aan taas waxa ay noqon doontaa si fudud suurtagal ahayn in ay inta badan ka mid ah guryaha iyo qalabka korontada.
