Ntchito yaikulu ya inductance ndi kusunga alternating current (kusunga mphamvu yamagetsi mu mawonekedwe a magnetic field), koma sichikhoza kusunga panopa (chindunji chamakono chikhoza kudutsa mu coil inductor popanda cholepheretsa).
Ntchito yaikulu ya capacitance ndi kusunga panopa mwachindunji (kusunga mphamvu yamagetsi mwachindunji pa mbale capacitor), koma sangathe kusunga alternating panopa (alternating panopa akhoza kudutsa capacitor popanda chopinga).
Inductance yoyambirira kwambiri idapezeka ndi wasayansi waku Britain Faraday mu 1831.
Zomwe zimagwiritsidwa ntchito ndizosintha zosiyanasiyana, ma mota, ndi zina.
Chithunzi chojambula cha koyilo ya Faraday (koyilo ya Faraday ndi koyilo yolumikizirana)
Mtundu wina wa inductance ndi self-coil inductance
Mu 1832, wasayansi wina wa ku America, Henry, anafalitsa nkhani yonena za kudzidzidzimutsa. Chifukwa cha chithandizo chofunikira cha Henry pazochitika zodzipangira yekha, anthu amatcha unit of inductance Henry, mwachidule monga Henry.
Chochitika chodzidzimutsa ndi chodabwitsa chomwe Henry adachipeza mwangozi pamene anali kuyesa electromagnet. Mu August 1829, pamene sukulu inali patchuthi, Henry anali kuphunzira za maginito amagetsi. Anapeza kuti koyiloyo inkatulutsa zopsereza zosayembekezereka mphamvu ikatha. Patchuthi chachilimwe cha chaka chotsatira, Henry anapitirizabe kuphunzira zoyesera zokhudzana ndi kudziletsa.
Potsirizira pake, mu 1832, pepala linasindikizidwa kuti litsimikizire kuti mu koyilo yokhala ndi zamakono, pamene kusintha kwatsopano, mphamvu yamagetsi yotchedwa electromotive mphamvu (voltage) idzapangidwa kuti ikhalebe yamakono. Choncho pamene mphamvu ya koyilo si kulumikizidwa, panopa amachepetsa nthawi yomweyo, ndipo koyilo adzapanga voteji mkulu kwambiri, ndiyeno ntchentche Henry anaona (mkulu voteji akhoza ionize mpweya ndi yochepa dera kutulutsa zipsera).
Koyilo yodziyendetsa
Faraday adapeza chodabwitsa cha electromagnetic induction, chomwe chili chofunikira kwambiri ndikuti kusintha kwa maginito kumapangitsa kuti pakhale mphamvu yamagetsi.
Mphamvu yokhazikika yokhazikika nthawi zonse imayenda mbali imodzi. Mu chipika chotsekedwa, zamakono zake sizisintha, kotero kuti madzi omwe akudutsa mu coil sasintha, ndipo maginito ake a maginito sangasinthe. Ngati kusinthasintha kwa maginito sikusintha, palibe mphamvu yopangira ma electromotive yomwe ingapangidwe, kotero kuti magetsi olunjika amatha kudutsa mosavuta pa coil ya inductor popanda chopinga.
Mu dera la AC, mayendedwe ndi kukula kwapano kudzasintha pakapita nthawi. Pamene AC ikudutsa mu coil inductor, pamene kukula ndi mayendedwe a panopa akusintha, maginito flux kuzungulira inductor adzasintha mosalekeza. Kusintha kwa maginito kumapangitsa kuti mphamvu ya electromotive ipangidwe, ndipo mphamvu ya electromotive iyi imalepheretsa kupita kwa AC!
Zoonadi, chopingachi sichimalepheretsa AC kudutsa 100%, koma imawonjezera zovuta za AC kudutsa (impedance ikuwonjezeka). Potsekereza AC kudutsa, gawo la mphamvu yamagetsi limasinthidwa kukhala mawonekedwe a maginito ndikusungidwa mu inductor. Iyi ndi mfundo ya inductor kusunga mphamvu yamagetsi
Mfundo yosungira ndi kutulutsa mphamvu yamagetsi inductor ndi njira yosavuta:
Pamene coil ikuwonjezeka-kuchititsa kuti maginito asinthe kusintha-maginito kusintha kwa maginito-kupanga reverse induced electromotive mphamvu (kusunga mphamvu yamagetsi)-kulepheretsa mphamvu yowonjezera
Mphamvu yamagetsi ikachepa - kuchititsa kuti maginito asinthe - kusintha kwa maginito - kutulutsa mphamvu yamagetsi yomwe imapangitsa mphamvu yamagetsi (kutulutsa mphamvu yamagetsi) - kutsekereza mphamvu yamagetsi kuti isatsike.
Mwachidule, inductor ndi wodzisunga, nthawi zonse kusunga chikhalidwe choyambirira! Amadana ndi kusintha ndipo amachitapo kanthu kuti aletse kusintha kwamakono!
Inductor ili ngati posungira madzi AC. Pamene panopa mu dera lalikulu, amasunga mbali yake, ndipo pamene panopa ali wamng'ono, amamasula kuti awonjezere!
