Mfundo yogwira ntchito ya inductance

Inductance ndikumangirira waya kukhala mawonekedwe a koyilo. Pamene panopa ikuyenda, mphamvu ya maginito idzapangidwa kumapeto kwa coil (inductor). Chifukwa cha mphamvu ya electromagnetic induction, imalepheretsa kusintha kwapano. Choncho, inductance imakhala ndi kukana pang'ono kwa DC (yofanana ndifupikitsa) ndi kukana kwakukulu kwa AC, ndipo kukana kwake kumagwirizana ndi mafupipafupi a chizindikiro cha AC. Kukwera kwa ma frequency a AC pano akudutsa mu chinthu chomwecho, kumapangitsanso kukana.

Inductance ndi chinthu chosungiramo mphamvu chomwe chimatha kusintha mphamvu yamagetsi kukhala mphamvu yamaginito ndikuyisunga, nthawi zambiri imakhala ndi mafunde amodzi okha. Inductance idachokera ku koyilo yachitsulo yomwe idagwiritsidwa ntchito ndi M. Faraday ku England mu 1831 kuti apeze chodabwitsa cha electromagnetic induction. Inductance imagwiranso ntchito yofunikira pamabwalo apakompyuta.
Makhalidwe a inductance: Kulumikizana kwa DC: kumatanthawuza kuti mu dera la DC, palibe chotchinga pa DC, chomwe chili chofanana ndi waya wowongoka. Kukaniza AC: Madzimadzi omwe amatchinga AC ndikupanga cholepheretsa china. Kukwera kwafupipafupi, kumapangitsanso kuti koyiloyo iwonongeke kwambiri.

Kutsekereza kwaposachedwa kwa koyilo ya inductance: mphamvu yodzipangira yokha yamagetsi mu inductance coil nthawi zonse imalimbana ndi kusintha kwaposachedwa kwa koyilo. Koyilo yochititsa chidwi imakhala ndi chotchinga pa AC pano. Kutsekereza kumatchedwa inductive reactance XL, ndipo unit ndi ohm. Ubale wake ndi inductance L ndi AC pafupipafupi f ndi XL=2nfL. Ma inductors amatha kugawidwa kukhala koyilo yapafupipafupi yotsamwitsa komanso koyilo yotsika pafupipafupi.

Kukonza ndi kusankha pafupipafupi: LC ikukonzekera dera lingapangidwe ndi kulumikizana kofanana kwa inductance coil ndi capacitor. Ndiko kuti, ngati ma frequency oscillation achilengedwe f0 a dera ndi ofanana ndi pafupipafupi f ya siginecha yosakhala ya AC, momwe zimachitikira komanso capacitive reactance ya dera nazonso ndizofanana, kotero kuti mphamvu yamagetsi yamagetsi imazungulira mmbuyo ndi mtsogolo mu inductance ndi capacitance, chomwe ndi chodabwitsa cha resonance cha dera la LC. Pa resonance, inductive reactance ndi capacitive reactance ya dera imakhala yofanana ndikubwerera. Kusintha kwa inductive kwa nthawi yonse yaposachedwa ndi yaying'ono kwambiri, ndipo kuchuluka kwapano ndi kwakukulu kwambiri (ponena za chizindikiro cha AC chokhala ndi f = ”f0″) LC resonant dera ili ndi ntchito yosankha ma frequency, ndipo imatha kusankha chizindikiro cha AC ndi pafupipafupi f.
Ma inductors alinso ndi ntchito zosefera ma sigino, kusefa phokoso, kukhazikika kwapano komanso kupondereza kusokoneza kwamagetsi.
