Yogwira kukana mu AC dera

dera magetsi amatenga pamaso pa kapangidwe kake angapo a zigawo zosiyana. Capacitors ndi zinthu inductance m'gulu dera kupeza zotsatira ambiri osiyanasiyana. Yogwira kukana Choncho alipo mu mawonekedwe a zinthu payekha, resistors ndi kulimbikira Kulumikizana. Physics amadza chifukwa cha mbali dera malamulo a otaya zochitika magetsi anaphunzira kwambiri bwinobwino, ndipo si wosiyana kwambiri kuchokera chikhalidwe cha nthenda ya magetsi, kapena mutamwa AC kapena DC voteji.

Yogwira kukana mu AC dera umagwira ntchito mofanana mu zonse kotunga voteji mode. Ndi chinthu pagona - zinthu za capacitance ndi inductance. Ngati dera gawo, mmene capacitor ndi chikugwirizana, si kwathunthu DC chigawo, ndi inductor pa izo ziribe mphamvu. Mu otaya wa panopa mwachindunji mu chimake ndi inductance ndi amakhudza yekha kulimbikira wa coils yogwira.

zinthu zosiyana kwambiri pofotokoza njira magetsi mu unyolo wa alternating panopa. Capacitors kukhala ochititsa, ndi inductor (kutsamwa koyilo wa thiransifoma ndi zina zotero.) Tatenga inductive reactance, ndipo nawonso, n'chofunikira zofunika kwambiri, ndi kukana zambiri si n'komwe.

Koma, koma, kufunika kwa mawerengedwe molondola kufunika kuganizira chigawo ichi. Kuti kumvetsa mmene kulimbikira yogwira koyilo ali pamodzi inductive, icho chiyenera ambiri kuganizira chipangizo muyezo inductor.

Mu ntchito ya chigawo dera chipangizo ichi sichina kuposa zimabweretsa ochititsa kuti a zosiyanasiyana machitidwe magetsi, electromechanical ndi zipangizo ndi zipangizo. Waukulu chizindikiro mtengo lidalembedwa ndi kudzikonda inductance. Ndiyeno, zimatengera yekha pa miyeso ya zojambula ndi zipangizo kupanga. Kufunika inductance si kusonkhezera ngakhale panopa kapena voteji. Ntchito inductors ndi Zosefera kwa phokoso yimitsira, ntchito zawo limalola kuwongola pulsations koyilo amathanso kudziunjikira mphamvu kuti chimagwiritsidwa ntchito kamangidwe madera resonant.

Kudziwa amadza kukana ali ndi ntchito inductor, ayenera kutengedwa ndi alternating panopa dera ndi chinthu limodzi, ndilo koyilo inductance. Kuwerengetsa udakali inductive reactance, zingatanthauze chophweka njira kuwerengera phindu okwana ndi Kuwonjezera wa makhalidwe awo mtheradi.

Koma mfundo imeneyi ili si kosavuta monga zingatanthauze. Kusiya maziko ongolankhula, fotokozani ntchito mu mchitidwe njira chimangirizo za udakali inductive reactance.

Kupeza zigoli okwana kumanga kansalu bwino. Limodzi ndi mwendo kukaniza ake, ndi ena - inductive. The hypotenuse chofanana ndi kukana okwana dera, amene ndi tanthauzo ndiyofanana ndi muzu lalikulu Muwerenge mabwalo a resistances udakali inductive.

Asayansi akuyendera njira iyi, kubala mfundo zolondola kwambiri zokhudza njira kunachitika mu dera AC amene zinthu ndi koyilo. Mu dongosolo la Chilamulo Ohm tingathe kugwiritsa ntchito mtengo wa impedance lapansi. Monga chiyenera zina kudziŵika kuti kukana kwambiri poyerekeza ndi inductive ndi angachite gawo kosangalatsa pakati panopa ndi voteji. N'chifukwa chake kupanga inductors ankagwiritsa ntchito kamangidwe ka pakati, amene amapereka ubwino kwambiri inductive reactance.
