Umgaqo we-inductor ogcina amandla ombane

Umsebenzi ophambili we-inductance kukugcina i-alternating current (ukugcina amandla ombane ngendlela ye-magnetic field), kodwa ayikwazi ukugcina ngoku ngokuthe ngqo (i-current ngqo ingadlula kwi-coil inductor ngaphandle kwesithintelo).

Umsebenzi oyintloko we-capacitance kukugcina ngoku ngokuthe ngqo (ukugcina amandla ombane ngokuthe ngqo kwiiplate ze-capacitor), kodwa ayikwazi ukugcina i-alternating current (i-alternating current ingadlula kwi-capacitor ngaphandle kwesithintelo).

Eyona inductance yamandulo yafunyanwa sisazinzulu saseBritani uFaraday ngo-1831.

Izicelo eziqhelekileyo ziziguquli ezahlukeneyo, iimoto, njl.

Olunye uhlobo lwe-inductance kuku-Ikhoyili ye-inductance

Ngomnyaka we-1832, uHenry, isazinzulu saseMelika, wapapasha iphepha malunga ne-self-induction phenomenon. Ngenxa yegalelo elibalulekileyo likaHenry kwinkalo ye-self-induction phenomenon, abantu babiza iyunithi ye-inductance Henry, efinyeziweyo njengoHenry.

I-self-induction phenomenon yinto eyafunyanwa nguHenry ngengozi xa wayesenza uvavanyo lwe-electromagnetic. NgoAgasti 1829, xa isikolo sasisekhefini, uHenry wayefundela imagnethi yombane. Wafumanisa ukuba ikhoyili yavelisa iintlantsi ezingalindelekanga xa umbane uqhawulwe. Ngeeholide zasehlotyeni zonyaka olandelayo, uHenry waqhubeka efunda imifuniselo enxulumene nokuziqhelanisa.

Ekugqibeleni, kwi-1832, iphepha lapapashwa ukugqiba ukuba kwikhoyili ekhoyo ngoku, xa utshintsho lwangoku, i-electromotive force induced (i-voltage) iya kuveliswa ukuze kugcinwe umbane wangaphambili. Ngoko ke xa unikezelo lwamandla coil luqhawulwe, langoku kuncipha ngoko nangoko, kwaye ikhoyili iya kuvelisa ombane ophezulu kakhulu, kwaye ke iintlantsi Henry wabona (ombane ophezulu ionize umoya kunye short-yesiphaluka ukuvelisa iintlantsi).

Ikhoyili ye-self-inductance

UFaraday ufumene isenzeko sokungeniswa kwe-electromagnetic, eyona nto iphambili kukuba ukutshintsha kwemagnethi kuya kuvelisa amandla e-electromotive.

Umsinga othe ngqo ozinzileyo uhlala uhamba kwicala elinye. Kwi-loop evaliweyo, i-current yayo ayitshintshi, ngoko i-current flowing kwi-coil ayitshintshi, kwaye i-flux yayo yamagnetic ayiyi kutshintsha. Ukuba i-flux yamagnetic ayitshintshi, akukho mandla ombane owenziweyo aya kuveliswa, ngoko ke umbane othe ngqo unokudlula ngokulula kwi-coil ye-inductor ngaphandle kokuphazamiseka.

Kwisekethe ye-AC, ulwalathiso kunye nobukhulu bangoku buya kutshintsha ngokuhamba kwexesha. Xa i-AC idlula i-coil ye-inductor, njengoko ubukhulu kunye nolwalathiso lwangoku lutshintsha, i-flux magnetic ejikeleze i-inductor iya kutshintsha ngokuqhubekayo. Utshintsho kwi-magnetic flux luya kubangela ukuveliswa kwamandla e-electromotive, kwaye la mandla e-electromotive athintele ukudlula kwe-AC!

Ngokuqinisekileyo, lo mqobo awuthinteli i-AC ukuba idlule i-100%, kodwa inyusa ubunzima bokudlula kwe-AC (i-impedance yanda). Kwinkqubo yokuthintela ukudlula kwe-AC, inxalenye yamandla ombane iguqulwa ibe yindlela yamagnetic field kwaye igcinwe kwi-inductor. Lo ngumgaqo we-inductor ogcina amandla ombane

Umgaqo wokugcina i-inductor kunye nokukhulula amandla ombane yinkqubo elula:

Xa i-coil yangoku inyuka-ebangela ukuba i-flux magnetic ejikelezileyo itshintshe-i-magnetic flux iyatshintsha-ivelisa amandla ombane owenziwe nge-reverse (ukugcina amandla ombane) -ukuthintela okwangoku ekunyuseni

Xa i-coil yangoku iyancipha-ebangela ukuba i-flux magnetic ejikelezileyo itshintshe-i-magnetic flux iyatshintsha-ivelisa ulwalathiso olufanayo lwe-electromotive force (ukukhulula amandla ombane) -ukuthintela okwangoku ekunciphiseni.

Ngelizwi, i-inductor i-conservative, ihlala igcina imo yangaphambili! Uluthiyile utshintsho kwaye uthatha inyathelo lokuthintela utshintsho lwangoku!

I-inductor ifana nedama lamanzi le-AC. Xa i-current in the circuit inkulu, igcina inxalenye yayo, kwaye xa ikhoyo incinci, iyayikhulula ukongeza!
