Zambiri za Resistance R, inductance L, ndi capacitance C

M'ndime yapitayi, tidakambirana za ubale wa Resistance R, inductance L, ndi capacitance C, apa tikambirana zambiri za iwo.

Ponena za chifukwa chake ma inductors ndi ma capacitor amapanga ma inductive and capacitive reactances mu AC mabwalo, akamanena za kusintha kwa magetsi ndi apano, zomwe zimapangitsa kusintha kwa mphamvu.

Kwa inductor, pamene panopa akusintha, maginito ake amasinthanso (kusintha mphamvu).Tonsefe tikudziwa kuti mu induction ya electromagnetic, mphamvu ya maginito yomwe imapangidwira nthawi zonse imalepheretsa kusintha kwa maginito oyambirira, kotero kuti nthawi zambiri zimawonjezeka, zotsatira za kulepheretsa kumeneku zimakhala zoonekeratu, zomwe ndi kuwonjezeka kwa inductance.

Mphamvu ya capacitor ikasintha, kuchuluka kwa ndalama pa mbale ya electrode kumasinthanso molingana.Mwachiwonekere, kuthamanga kwamagetsi kumasintha, mofulumira komanso kusuntha kwa kuchuluka kwa ndalama pa mbale ya electrode.Kusuntha kwa kuchuluka kwa ndalamazo ndiko kwenikweni.Mwachidule, kuthamanga kwamagetsi kumasintha, kukulirakulira komwe kumadutsa mu capacitor.Izi zikutanthawuza kuti capacitor palokha imakhala ndi zotsatira zochepa zolepheretsa pakalipano, zomwe zikutanthauza kuti capacitive reactance ikuchepa.

Mwachidule, inductance ya inductor imagwirizana mwachindunji ndi mafupipafupi, pamene mphamvu ya capacitor imakhala yosiyana kwambiri ndi nthawi zambiri.

Kodi pali kusiyana kotani pakati pa mphamvu ndi kukana kwa inductors ndi capacitors?

Zotsutsa zimagwiritsa ntchito mphamvu m'mabwalo onse a DC ndi AC, ndipo kusintha kwa magetsi ndi zamakono nthawi zonse kumagwirizanitsidwa.Mwachitsanzo, chithunzi chotsatirachi chikuwonetsa ma voteji, apano, ndi ma curve amphamvu a resistors mu mabwalo a AC.Kuchokera pa graph, zikhoza kuwoneka kuti mphamvu yotsutsa nthawi zonse yakhala yaikulu kuposa kapena yofanana ndi zero, ndipo sidzakhala yocheperapo kuposa zero, zomwe zikutanthauza kuti wotsutsa wakhala akutenga mphamvu zamagetsi.

M'mabwalo a AC, mphamvu yogwiritsidwa ntchito ndi resistors imatchedwa mphamvu yapakati kapena mphamvu yogwira ntchito, yomwe imatchulidwa ndi chilembo chachikulu P. Zomwe zimatchedwa mphamvu yogwira ntchito zimangoimira makhalidwe ogwiritsira ntchito mphamvu za chigawocho.Ngati chigawo china chili ndi mphamvu zogwiritsira ntchito mphamvu, ndiye kuti mphamvu yogwiritsira ntchito mphamvu imayimiridwa ndi mphamvu yogwira P kusonyeza kukula (kapena liwiro) la mphamvu zake.

Ndipo ma capacitors ndi inductors samadya mphamvu, amangosunga ndikutulutsa mphamvu.Pakati pawo, ma inductors amatenga mphamvu yamagetsi mu mawonekedwe a maginito otulutsa maginito, omwe amamwa ndikusintha mphamvu zamagetsi kukhala maginito mphamvu, ndiyeno amamasula mphamvu ya maginito mu mphamvu yamagetsi, kubwereza mosalekeza;Momwemonso, ma capacitor amatenga mphamvu zamagetsi ndikuzisintha kukhala mphamvu yamagetsi, kwinaku akutulutsa mphamvu zamagetsi ndikuzisintha kukhala mphamvu zamagetsi.

Inductance ndi capacitance, njira yogwiritsira ntchito ndi kutulutsa mphamvu zamagetsi, sizimadya mphamvu ndipo momveka bwino sizingayimire mphamvu yogwira ntchito.Kutengera izi, akatswiri a sayansi ya zakuthambo atanthauzira dzina latsopano, lomwe ndi mphamvu yogwira ntchito, yoimiridwa ndi zilembo Q ndi Q.
