Le reactance ezenza ukuba wesekethe AC

Ukuxhathisa kwi indlela yombane kukuba kweentlobo ezimbini - iyasebenza izidubuli. resistors Active zimelwe, igqengezelayo, ukufudumeza imibhijelo njalo njalo. Ngamanye amazwi, zonke izinto apho ukuhamba yangoku engaqhubi ngqo umsebenzi luncedo okanye, kwimeko ekhethekileyo, ukuze avelise ubushushu Umqhubi oyifunayo. Ngenxa yoko, i-jet - Gnostic. Oku kubhekisela reactance capacitive kunye ezenza. Iziqalelo wesekethe ukuba reactance, indlela umbane zenzeka conversion amandla eliphakathi ezahlukeneyo. A capacitor (capacitance) oqokelela isigxina, koko ithumela kwi loop. Omnye umzekelo - le reactance ezenza ukuba le coil, apho isabelo amandla ombane iguqulelwa ibe yintsimi ngemagnethi.

Enyanisweni, "olunyulu" okanye reactances iyasebenza na. Soloko icandelo elijongene ekhoyo. Ngokomzekelo, xa kubalwa iingcingo imida igunya-elide umgama, ithathele ingqalelo kuphela luvukelo, kodwa capacitive. Yaye kucingwa reactance zokuqala, kufuneka kukhunjulwe ukuba zombini izinikezeli kunye nonikezelo lwamandla benza utshintsho abanye izibalo.

Ngokubona luvukelo lilonke inxalenye yesekethe, kuyimfuneko ukuba ulisonge amacandelo iyasebenza izidubuli. Ngaphezu koko, ukuze ufumane imali ngqo imisebenzi yesiqhelo zemathematika akunakwenzeka, ngoko sebenzisa zejiyometri (kumda wesangqa) indlela yokwakha. Wakha unxantathu sokunene cathetus ezimbini ukuvimba esebenzayo zokuqala, kwaye hypotenuse - ngokupheleleyo. Ubude inxalenye ehambelana amaxabiso yangoku.

Cinga reactance ezenza kumphathi wesekethe AC. Ubonise isekethi elula kuqulethe umthombo wamandla (EMF, E), i resistor (icandelo resistive, R) kunye coil (inductance, L). Ekubeni reactance ezenza kungenxa EMF self-olubangelwa (E B) xa Akubuya ye-coil, kucacile ukuba kwanda inductance yesekethe kunye nexabiso indyebo yangoku ayahamba na wesekethe.

umthetho Ohm kaThixo ngenxa yale wesekethe sifana:

E + E B = mna R.

Emva kokuba izigqibo kwexesha yemvelaphi the current (I PR) ukubala self-kuFacebook:

E si = -L * I Ave.

"- 'phawu kwi equation ibonisa ukuba isiphumo E si sibhekiswe ukutshintsha ixabiso yangoku. Lenz umthetho ithi xa kukho naluphi na utshintsho EMF self-wayenga lwangoku. Ekubeni utshintsho ezinjalo kwiisekethe AC zizinto zendalo (kwaye rhoqo), i-E B yakha ukumelana emandla okanye ukuba ukuziziliza nayo yinyaniso. Kwimeko apho kukho umthombo wamandla we yangoku ngqo , olu lwalamano akanelisekanga yaye xa ukuzama ukudibanisa i coil (inductance) kwisiphaluka onjalo short-circuit yenzekile Classic

Ukoyisa lo E B umbane kufuneka generate umahluko amandla kwiziphumo coil ukuba ngokwaneleyo, ubuncinane E ukunganyangeki si imbuyekezo. Kulandela:

U = ikati -E si.

Ngamanye amazwi, le ombane ngaphesheya inductor yi ngamanani ulingane nomkhosi electromotive of self-induction.

Ekubeni ngokwandayo ngoku kwisekethe kwandisa lo mhlaba otsalayo ke yenza entsimini eddy ebangela Ukukhula inductance miso, umntu uyakwazi ukubona ukuba kukho shift kwisigaba phakathi ombane kunye yangoku. Ngoko omnye phawu: ngokuba i-self-induction EMF kuthintela naluphi na utshintsho ngoku, xa yandisa (ixesha lokuqala kwikota ye sinusoid in) endle counter is generated, kodwa ukuwa (ikota yesibini) ngokuchasene - i kwezi- yangoku codirectional kunye nesiseko. Oko kukuthi, ukuba postulate khona i umthombo wamandla ofanelekileyo ngaphandle nokumelana lwangaphakathi kunye inductance ngaphandle icandelo esebenzayo, amandla ukungcangcazela "umthombo - coil" kungavela ngokungenammiselo.
