Banana capacitance na capacitor: yanayi da kuma babban halaye

Duka a cikin masana'antu da kuma a cikin rayuwar yau da kullum sau da yawa na bukatar halittar wani babban yawan tabbatacce kuma korau lantarki zargin. A fili yake cewa da wutar lantarki na jikinsu da kuma cikin electrostatic shigar da su sa shi ba zai yiwu ba. Sai dai itace cewa kana bukatar wani musamman na'urar. Irin wannan na'ura hidima a matsayin condenser.

A capacitor ne mai sauki tsarin kunsha na dielectric raba biyu faranti. Yana da muhimmanci sosai cewa kauri daga cikin insulator ya kananan idan aka kwatanta da girman wadannan guda faranti, watau conductors.

A sauki nau'i na lantarki capacitive na'urar ne wani lebur capacitor, wanda shi ne wani hadadden na biyu karfe faranti rabu da wani dielectric. Idan wadannan faranti dauki lantarki halin yanzu, da gwada yawa darajar tashin hankali tasowa tsakanin lantarki filin ne kusan biyu har fiye da sau guda tsanani a daya daga wadannan faranti.

A mafi muhimmanci nuna alama na wannan tsarin ne lantarki capacitance. Banana capacitance na capacitor cikin sharuddan electro sansanonin daidai da rabo daga cikin cajin na daya daga cikin faranti da irin ƙarfin lantarki amfani tsakanin conductors na wannan na'urar. A general, da wutar lantarki, capacitance na capacitor ne kamar haka:

C = q / U

Idan matsayi na faranti a sarari ya zauna canzawa na dogon lokaci, da wutar lantarki, capacitance na capacitor da ya rage m (ko da na gwada yawa cajin a kan faranti).

A kasa da kasa System of jiki ma'aunai na lantarki capacitance na capacitor da aka auna a farads (F). A cewar wannan rarrabuwa, daya farad characterizes lantarki capacitance irin wannan na'urar a cikin abin da ƙarfin lantarki tsakanin insulators ne daya volt, da kuma adadin cajin wanda aka yi amfani da zuwa kwano, shi ne daidaita daya wuya.

A gaskiya ma, daya farad - wannan shi ne manya-manyan darajar, don haka aka fi amfani da raka'a kamar microfarad, kuma ko da Nanofarad PF.

Flat lantarki capacitance na capacitor zai dogara ne a kan yankin na ta wayoyin da za a karu yayin da rage tazarar dake tsakanin su. Don muhimmanci ƙara lantarki damar wadannan na'urorin da aka gabatar tsakanin conductors ko wani dielectric.

A mafi yawan lokuta, da wayoyin ga capacitors sanya daga bakin ciki tsare da GASKET a matsayin core amfani da takarda, Mica ko yumbu. Shi ne daidai da kayan hidima a matsayin tushen ga dielectrics, capacitors, da kuma samun su da sunan - takarda, yumbu, iska, Mica. Fairly tartsatsi a cikin 'yan shekarun samu da electrolytic capacitors da suke da isasshe m girma da babba lantarki iya aiki. Saboda wadannan halaye, suna amfani da ko'ina a iyali kayan, kazalika da rectifier halin yanzu.

Capacitors ne daya daga cikin mafi muhimmanci lantarki kayan, ba tare da wanda zai zama kawai zai yiwu ba a yi rinjaye na iyali, kuma lantarki kayan.
