Resistance R, inductance L, ndi capacitance C

Resistance R, inductance L, ndi capacitance C ndi zigawo zazikulu zitatu ndi magawo ozungulira, ndipo mabwalo onse sangathe kuchita popanda magawo atatuwa (mmodzi wa iwo).Chifukwa chomwe iwo ali zigawo ndi magawo ndi chifukwa R, L, ndi C amaimira mtundu wa chigawo, monga chigawo chotsutsa, ndipo kumbali ina, amaimira nambala, monga mtengo wotsutsa.

Izi ziyenera kunenedwa mwapadera apa kuti pali kusiyana pakati pa zigawo zomwe zili mu dera ndi zigawo zenizeni za thupi.Zomwe zimatchedwa zigawo mu dera kwenikweni ndi chitsanzo chabe, chomwe chingathe kuimira khalidwe linalake la zigawo zenizeni.Mwachidule, timagwiritsa ntchito chizindikiro kuti tiyimire khalidwe linalake la zida zenizeni, monga zotsutsa, ng'anjo zamagetsi, ndi zina Zowotcha zamagetsi zamagetsi ndi zigawo zina zimatha kuimiridwa m'mabwalo pogwiritsa ntchito zigawo zotsutsa monga zitsanzo zawo.

Koma zida zina sizingathe kuimiridwa ndi chinthu chimodzi chokha, monga kupiringa kwa injini, yomwe ndi koyilo.Mwachiwonekere, ikhoza kuimiridwa ndi inductance, koma kupukuta kumakhalanso ndi mtengo wotsutsa, kotero kukana kuyenera kugwiritsidwanso ntchito kuimira mtengo wotsutsa.Chifukwa chake, popanga ma injini oyenda mozungulira, iyenera kuyimiridwa ndi kuphatikiza kwa inductance ndi kukana.

Kukaniza ndikosavuta komanso kodziwika bwino.Malinga ndi lamulo la Ohm, kukana R=U/I, kutanthauza kuti kukana ndi kofanana ndi voteji yomwe imagawidwa ndi masiku ano.Kuchokera pamalingaliro a mayunitsi, ndi Ω=V/A, kutanthauza kuti ma ohms ndi ofanana ndi ma volts ogawidwa ndi amperes.Mudera, kukana kumayimira kutsekereza komwe kumachitika pakali pano.Kukana kukulirakulira, kumapangitsanso kutsekereza kwamphamvu… Mwachidule, kukana sikunganene.Kenako, tikambirana za inductance ndi capacitance.

M'malo mwake, inductance imayimiranso mphamvu yosungira mphamvu ya zigawo za inductance, chifukwa mphamvu ya maginito imakhala ndi mphamvu zambiri.Minda ya maginito imakhala ndi mphamvu, chifukwa mwanjira imeneyi, mphamvu za maginito zimatha kugwiritsira ntchito mphamvu ya maginito ndikugwira ntchito.

Kodi pali mgwirizano wotani pakati pa inductance, capacitance, ndi resistance?

Inductance, capacitance iwowo alibe chochita ndi kukana, mayunitsi awo ndi osiyana kotheratu, koma ndi osiyana mu AC mabwalo.

Mu DC resistors, inductance ndi yofanana ndi dera lalifupi, pamene capacitance ndi yofanana ndi dera lotseguka (lotseguka).Koma m'mabwalo a AC, inductance ndi capacitance zimapanga zosiyana zotsutsana ndi kusintha kwafupipafupi.Panthawiyi, kutsutsa sikumatchedwanso kukana, koma kumatchedwa reactance, yomwe imayimiridwa ndi chilembo X. Mtengo wotsutsa wopangidwa ndi inductance umatchedwa inductance XL, ndipo mtengo wotsutsa wopangidwa ndi capacitance umatchedwa capacitance XC.

Inductive reactance ndi capacitive reactance ndizofanana ndi zopinga, ndipo mayunitsi ake ali mu ohms.Choncho, iwonso amaimira kutsekereza zotsatira za inductance ndi capacitance pa panopa mu dera, koma kukana sikusintha ndi pafupipafupi, pamene inductive reactance ndi capacitive reactance kusintha ndi pafupipafupi.
