Uxhathiso esbnzyo kwi kwisekethe AC

yombane ithatha ubukho kumafa zayo ezininzi ezahlukeneyo. Capacitors kunye nezinye izinto inductance zifakiwe beesekethe ukuze afumane iziphumo ezininzi ezahlukahlukeneyo. Ngoko nokumelana Active ekhona uhlobo lweziqalelo ngamnye, resistors kunye ukungawi iintambo. Physics nempembelelo icandelo wesekethe imithetho sokuqukuqela iziganeko zombane wafundela kakhulu kakuhle, kwaye kakhulu ezahlukene ukusuka uhlobo ukuhamba umbane, nokuba phantsi kwempembelelo AC okanye DC ombane.

uxhathiso Active kwisekethe AC isebenza ngendlela efanayo njengoko engapheli yonikezelo imo ombane. Akuve enye into - amasuntswana capacitance kunye inductance. Ukuba isabelo yesekethe, apho capacitor elidityaniswe, ayikho ngokupheleleyo licandelo DC, lo inductor kuwo akukho isiphumo. Xa ukuhamba ngayo ngoku ngqo kwi lwalo kunye inductance kuchaphazela kuphela kweelana jiko esebenzayo.

izinto ezahlukeneyo xa echaza iinkqubo zombane kwi umqokozo alternating current. Capacitors baba abaqhubi, kunye inductor (coil ziliminxe le transformer, njalo njalo.) Zuza reactance ezenza ukuba, kwaye, nayo, idlala indima ebaluleke kakhulu ngakumbi, yaye uxhathiso idla nje azithathelwa ngqalelo.

Kodwa ke, nangona kunjalo, imfuneko ukuze kubalwe ngokuchanekileyo kufuneka ukuba uyithathele ingqalelo eli candelo. Ukuqala ukuqonda indlela uxhathiso ebonakalayo Ikhoyili kudityaniswe kunye ezenza ukuba, kufuneka ngokubanzi ingqalelo sixhobo inductor eqhelekileyo.

Xa indima kwicandelo wesekethe a esi sixhobo nto ngaphezu njengento vuvabyi ye ezininzi iinkqubo zombane, electromechanical kunye elektronikhi kunye nezixhobo. Ixabiso ephambili parameter usebenzisa self-inductance. Loo nto, kuxhomekeke kuphela kumlinganiselo zejiyometri nezinto ngawo. Kwi ixabiso inductance akuthethi nefuthe nanto ngoku okanye ombane. Isicelo inductors amacebo ukuze ingcinezelo ingxolo, ukusetyenziswa ivumela smoothing pulsations coil kwakhona angemi amandla ukuba lisetyenziswa kuyilo iziphaluka resonant.

Ukuze uhlaziye ukuxhathisa akuniki a inductor umsebenzi, kufuneka kuqwalaselwe isekethe ifildi omiyo into enye, nto leyo inductance coil. Ukubala esebenzayo kunye reactance ezenza ukuba, kubonakala indlela elula ukubala ixabiso lilonke ke ukongeza lwamaxabiso yabo epheleleyo.

Kodwa ezi zithethe oku kangangoko kubonakala lula. Ekususeni isiseko senkolelo, ukuchaza ukusetyenziswa xa kusenziwa le indlela summation of reactance esebenzayo ezenza.

Ukuze ufumane inqaku elipheleleyo ukwakha unxantathu tye. Elinye umlenze ukumelana yakhe, kunye nabanye - ezenza ukuba. Le hypotenuse ilingana uxhathiso iyonke yaloo mmandla, apho ngokwenkcazo ilingana ingcambu ka'B udibaniso lwezikweri le resistances iyasebenza ezenza.

Izibalo kuphunyezwa ngale ndlela, athwale ulwazi oluchanekileyo ngakumbi malunga neenkqubo ezikhoyo kwisekethe AC ogama iziqalelo ke coil. Kwifomula yoMthetho Ohm kaThixo singakwazi ukusebenzisa ixabiso amanzi. Njengoko Kufuneka kuqatshelwe ukuba amelane ebonakalayo xa kuthelekiswa nezi ziqhelekileyo ezenza ukuba zinganefuthe shift kwisigaba phakathi yangoku kunye ombane. Kungenxa yoko le nto nokuveliswa inductors ezisetyenziswa uyilo undoqo, nto leyo enika eziluncedo ezibalulekileyo reactance ezenza.
