Umgomo wokusebenza we-inductance

I-inductance iwukusonga ucingo lube sesimweni sekhoyili.Lapho ukugeleza kwamanje, insimu enamandla kazibuthe izokwakhiwa emikhawulweni yomibili yekhoyili (inductor).Ngenxa yomphumela wokungeniswa kwe-electromagnetic, kuzovimbela ushintsho lwamanje.Ngakho-ke, i-inductance inokumelana okuncane ku-DC (okufana nesifunda esifushane) nokumelana okuphezulu kwe-AC, futhi ukumelana kwayo kuhlobene nemvamisa yesignali ye-AC.Lapho iphakama imvamisa yamanje ye-AC edlula ku-elementi efanayo yokungenisa, likhulu inani lokumelana.

I-inductance iyingxenye yokugcina amandla engaguqula amandla kagesi abe amandla kazibuthe futhi iwagcine, ngokuvamile ngokujika okukodwa kuphela.I-inductance yaqalwa kukhoyili ye-iron-core eyasetshenziswa ngu-M. Faraday e-England ngo-1831 ukuze kutholwe ukwenzeka kokungeniswa kwe-electromagnetic.I-inductance nayo idlala indima ebalulekile kumasekhethi kagesi.
Izici ze-inductance: Ukuxhumeka kwe-DC: kubhekisela kulokho kusekethe ye-DC, awukho umphumela wokuvinjwa ku-DC, olingana nentambo eqondile.Ukumelana ne-AC: Uketshezi oluvimba i-AC futhi lukhiqize i-impedance ethile.Lapho imvamisa iphakeme, i-impedance ekhiqizwa ikhoyili inkulu.

Umthelela wamanje wokuvinjwa kwekhoyili ye-inductance: amandla e-electromotive azenzelayo kukhoyili ye-inductance ahlale amelana noshintsho lwamanje lwekhoyili.Ikhoyili ye-inductive inomphumela wokuvimba ku-AC yamanje.Umphumela wokuvimba ubizwa ngokuthi i-inductive reactance XL, kanti iyunithi ithi ohm.Ubudlelwano bayo ne-inductance L kanye ne-AC frequency f yi-XL=2nfL.Ama-inductors angahlukaniswa kakhulu abe ikhoyili yokuklinya amafrikhwensi aphezulu kanye nekhoyili yokuminyanisa eyifrikhwensi ephansi.

Ukukhetha nokukhetha imvamisa: Isekethe ye-LC tuning ingakhiwa ngokuxhuma okufanayo kwekhoyili ye-inductance kanye ne-capacitor.Okusho ukuthi, uma imvamisa yemvelo ye-oscillation f0 yesekethe ilingana nemvamisa f yesiginali engeyona eye-AC, ukusabela kwe-inductive kanye nokusabela kwe-capacitive kwesekethe nakho kuyalingana, ngakho-ke amandla kazibuthe kagesi azulazula aye emuva naphambili ku-inductance futhi. i-capacitance, okuyi-resonance phenomenon yesekethe ye-LC.Phakathi ne-resonance, i-inductive reactance kanye ne-capacitive reactance yesekethe kuyalingana futhi kuyahlehla.Ukusabela kwe-inductive kwengqikithi yamanje yesekethe kuncane kakhulu, futhi inani lamanje likhulu (kubhekiselwa kusiginali ye-AC eno-f=”f0″).Isekhethi ye-LC resonant inomsebenzi wokukhetha imvamisa, futhi ingakhetha isignali ye-AC nge-frequency ethile.
Ama-inductors nawo anemisebenzi yokuhlunga amasiginali, umsindo wokuhlunga, ukusimamisa kwamanje kanye nokucindezela ukuphazamiseka kwe-electromagnetic.
