Capacitance electrical capacitor: ubunjalo kanye izici eziyinhloko

Kokubili umkhakha futhi ekuphileni kwansuku zonke ngokuvamile kudinga kudalwa inqwaba emihle nemibi amacala kagesi. Kuyacaca ukuthi nge kukagesi izidumbu kanye le lokungeniswa electrostatic ukuba kungenzeki. It kuvela ukuthi badinga idivayisi ekhethekile kuwe. idivayisi olunjalo lungamandla epholisayo.

I capacitor uhlelo elula eyayakhiwa Kwe-dielectric Heating esasihlukanisa plate amabili. Kubalulekile kakhulu ukuthi ukushuba we yisivikelo lalilincane kuqhathaniswa ubukhulu yalezi amapuleti efanayo, abaqhubi isb.

Ifomu elula kagesi kudivayisi capacitive kuyinto capacitor flat, okuyinto eziyinkimbinkimbi izingqimba ezimbili metal ahlukaniswe Kwe-dielectric Heating. Uma lezi amapuleti ukuthatha kagesi, ukubaluleka ambalwa ukungezwani ezivukayo phakathi emkhakheni kagesi cishe amabili izikhathi ephakeme kunaleyo umfutho efanayo ngesikhathi esisodwa salezi amapuleti.

I kuyinkomba ebaluleke kakhulu yokuthi lesi simiso capacitance kagesi. capacitance kagesi we capacitor ngokuya lezisekelo electro lilingana ratio isiyalezo omunye amapuleti ukuze voltage isicelo phakathi babashayeli kule divayisi. Ngokuvamile, capacitance kagesi capacitor simiswe ngalendlela lelandzelako:

C = q / U

Uma isikhundla namapulethi isikhala uhlala ingashintshiwe isikhathi eside, capacitance kagesi capacitor alushintshi (kungakhathaliseki ukuthi icala ambalwa ubeke amapuleti).

Ngo-International System kokulinganisela ngokomzimba of capacitance kagesi capacitor ulinganiswa farads (F). Ngokusho lokhu ngezigaba, omunye Farad ephawula capacitance kagesi idivayisi okuzofakwa kuyo voltage phakathi insulators ingenye volt, futhi inani ophethe lapho lisetshenziswa ipuleti, ilingana komunye elengayo.

Empeleni, omunye Farad - lena Inani elikhulu kakhulu, ngakho ngokuvamile ezisetshenziswa amayunithi ezifana microfarad, ngisho Nanofarad PF.

Flat capacitance kagesi capacitor kuzoncika endaweni electrode yayo futhi izokwenyuka ngenkathi ekunciphiseni ibanga elibahlukanisile. Ukwandisa amandla kagesi alamathuluzi yethulwa phakathi babashayeli noma kwenye Kwe-dielectric Heating.

Ezimweni eziningi, le electrode ngokuba capacitors elenziwe ucwecwe mncane futhi gasket njengendlela core esetshenziswa iphepha, mica noma sobumba. Kuyinto ngokuhambisana impahla ukukhonza njengoba isisekelo sokuthethelelwa dielectrics, capacitors, bese igama lakhe - iphepha, ngobumba, emoyeni, mica. Ngiphephile okwandile eminyakeni yamuva wathola capacitors electrolytic ukuthi kukhona ngokwanele Ubukhulu compact babe eside umthamo kagesi. Ngenxa yalezi zimfanelo, basuke kabanzi izinto zasendlini, kanye wamanje rectifier.

Capacitors ungomunye zikagesi ezibalulekile kunazo zikagesi, ngaphandle kwalokho kuyoba akunakwenzeka ukuba abe iningi yasendlini futhi basebenzise izinto zikagesi.
