Umgomo we-inductor ogcina amandla kagesi

Umsebenzi oyinhloko we-inductance ukugcina i-alternating current (ukugcina amandla kagesi ngendlela yamagnetic field), kodwa ayikwazi ukugcina i-direct current (i-direct current ingadlula ikhoyili ye-inductor ngaphandle kwesithiyo).

Umsebenzi oyinhloko we-capacitance ukugcina i-current ngqo (ukugcina amandla kagesi ngokuqondile kumapuleti e-capacitor), kodwa ayikwazi ukugcina i-alternating current (i-alternating current ingadlula ku-capacitor ngaphandle kwesithiyo).

I-inductance yokuqala kakhulu yatholwa usosayensi waseBrithani uFaraday ngo-1831.

Izicelo ezijwayelekile ziyi-transformer ehlukahlukene, ama-motor, njll.

Olunye uhlobo lwe-inductance yi-self-ikhoyili ye-inductance

Ngo-1832, uHenry, usosayensi waseMelika, wanyathelisa iphepha mayelana nokwenzeka kokuzingenisa. Ngenxa yeqhaza elibalulekile lika-Henry emkhakheni we-self-induction phenomenon, abantu babiza i-unit of inductance ngokuthi Henry, efushanisiwe ngokuthi u-Henry.

Isenzo sokuzingenisa siyisimanga uHenry asithola ngephutha lapho enza ukuhlola kukazibuthe kagesi. Ngo-August 1829, lapho isikole siseholidini, uHenry wayefunda ngozibuthe kagesi. Uthole ukuthi ikhoyili ikhiphe izinhlansi ebezingalindelekile ngesikhathi ugesi unqanyulwa. Eholidini lasehlobo lonyaka olandelayo, uHenry waqhubeka nokutadisha izivivinyo ezihlobene nokuzingenisa.

Ekugcineni, ngo-1832, iphepha lanyatheliswa ukuze liphethe ngokuthi kukhoyili enamanje, lapho izinguquko zamanje, kuzokwenziwa amandla e-electromotive (voltage) ukuze kugcinwe amandla okuqala. Ngakho-ke lapho amandla ekhoyili enqanyulwa, i-current iyancipha ngokushesha, futhi ikhoyili izokhiqiza i-voltage ephezulu kakhulu, bese kuvela izinhlansi ezabonwa nguHenry (i-voltage ephezulu ingenza i-ionize emoyeni kanye ne-short-circuit ukukhiqiza izinhlansi).

Ikhoyili ye-self-inductance

U-Faraday uthole isenzakalo sokungeniswa kwe-electromagnetic, into esemqoka kakhulu ukuthi ukuguquguquka kazibuthe kuzokhiqiza amandla e-electromotive.

Amandla aqondile aqinile ahlala ehamba ngendlela eyodwa. Ku-loop evaliwe, i-current yayo ayishintshi, ngakho-ke i-current egeleza ikhoyili ayishintshi, futhi i-flux yayo yamagnetic ngeke ishintshe. Uma i-flux kazibuthe ingashintshi, awekho amandla e-electromotive akhangisiwe azokhiqizwa, ngakho-ke amandla aqondile angadlula kalula kukhoyili ye-inductor ngaphandle kokuvinjwa.

Kumjikelezo we-AC, isiqondiso nobukhulu bamanje kuzoshintsha ngokuhamba kwesikhathi. Lapho i-AC idlula ikhoyili ye-inductor, njengoba ubukhulu nesiqondiso samanje kushintsha, ukugeleza kazibuthe okuzungeze i-inductor nakho kuzoshintsha ngokuqhubekayo. Ukushintsha kokuguquguquka kazibuthe kuzodala ukukhiqizwa kwamandla e-electromotive, futhi lamandla e-electromotive avele avimbe ukudlula kwe-AC!

Yebo, lesi sithiyo asivimbeli i-AC ukuthi idlule ku-100%, kodwa kwandisa ubunzima bokudlula kwe-AC (i-impedance iyanda). Enqubweni yokuvimbela ukudlula kwe-AC, ingxenye yamandla kagesi iguqulwa ibe uhlobo lwezibuthe futhi igcinwe ku-inductor. Lona umgomo we-inductor ogcina amandla kagesi

Umgomo wokugcina i-inductor kanye nokukhulula amandla kagesi kuyinqubo elula:

Lapho i-coil yamanje ikhula-okubangela ukuguquguquka kazibuthe okuzungezile-izinguquko ze-magnetic flux-okukhiqiza amandla e-electromotive induction reverse (ukugcina amandla kagesi) -ukuvimbela wamanje ekukhuphukeni

Lapho ikhoyili yamanje incipha—okubangela ukuguquguquka kazibuthe okuzungezile ukuba kushintshe—ukuguquguquka kazibuthe—okukhiqiza amandla e-electromotive amandla afanayo (ukukhulula amandla kagesi)—kuvimba amandla amanje ekuncipheni.

Ngamafuphi nje, i-inductor iyi-conservative, njalo igcina isimo sokuqala! Uyaluzonda uguquko futhi uthatha isinyathelo ukuvimbela ushintsho lwamanje!

I-inductor ifana nedamu lamanzi le-AC. Lapho i-current in the circuit inkulu, igcina ingxenye yayo, futhi lapho yamanje incane, iyayikhulula ukuze yengeze!

Okuqukethwe kwe-athikili kuvela ku-inthanethi
