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 ndi koyilo yotsika pafupipafupi.

Kukonza ndi kusankha pafupipafupi: LC ikukonzekera dera lingapangidwe ndi kulumikizana kofanana kwa inductance coil ndi capacitor.Ndiye kuti, ngati ma frequency achilengedwe a oscillation f0 a dera ndi ofanana ndi ma frequency f a siginecha yosakhala ya AC, kuyankha kwa inductive ndi capacitive reactance ya dera ilinso yofanana, kotero mphamvu yamagetsi yamagetsi imayenda mmbuyo ndi mtsogolo mu inductance ndi capacitance, chomwe ndi chodabwitsa cha resonance ya dera la LC.Pa resonance, inductive reactance ndi capacitive reactance ya dera imakhala yofanana ndikubwerera.Kachitidwe kochititsa chidwi kamene kalikonse kamene kakuzungulirako ndi kakang'ono kwambiri, ndipo kuchuluka kwapano ndi kwakukulu kwambiri (potengera chizindikiro cha AC chokhala ndi f=”f0″).Dera la LC resonant lili ndi ntchito yosankha ma frequency, ndipo limatha kusankha chizindikiro cha AC ndi ma frequency ena f.
Ma inductors alinso ndi ntchito zosefera ma sigino, kusefa phokoso, kukhazikika kwapano komanso kupondereza kusokoneza kwamagetsi.
