Passive chigawo ndi mtundu wa chigawo chamagetsi. Chifukwa mulibe magetsi mmenemo, kuyankhidwa kwa chizindikiro chamagetsi sikungokhala komanso kumvera. Chizindikiro chamagetsi chimangodutsa pagawo lamagetsi molingana ndi makhalidwe oyambirira, choncho amatchedwanso passive component.
Pali mitundu itatu ikuluikulu yazigawo zomwe zimagwira ntchito: capacitor, inductor ndi resistor, zomwe ndizofunikira kwambiri pakompyuta.

Capacitor

Ma capacitors ndi omwe amapezeka kwambiri pamagetsi amagetsi. Amasunga ndi kumasula mphamvu yamagetsi mu mawonekedwe a magetsi osasunthika. Iwo ali olekanitsidwa pakati pa zipangizo conductive pa mizati awiri ndi TV ndi sitolo mphamvu yamagetsi pakati pawo.

Inductor

Inductor ndi gawo lomwe lingasinthe mphamvu yamagetsi kukhala mphamvu yamagetsi ndikuyisunga. Mfundo yake yogwirira ntchito ndi yakuti pamene kusinthasintha kwamakono kumadutsa muwaya, kusinthasintha kwa maginito kumapangidwira mkati ndi kuzungulira waya. Ntchito yake yayikulu ndikudzipatula ndikusefa chizindikiro cha AC kapena kupanga chigawo cha harmonic chokhala ndi ma capacitors ndi resistors. Ma inductors amathanso kugawidwawodzipangitsandi mutual inductor.

Wodzipangira yekha

Pamene koyiloyo ikudutsa, mphamvu ya maginito imapangidwa mozungulira koyiloyo. Pamene panopa akusintha, mphamvu ya maginito yozungulira imasinthanso moyenera. Mphamvu ya maginito yomwe yasinthidwa imatha kupanga koyiloyo yokha kupanga mphamvu ya electromotive (induced electromotive force), yomwe imadzipangitsa yokha.
Zida zamagetsi zomwe zimakhala ndi chiwerengero china cha kutembenuka ndipo zimatha kupanga zodzikongoletsera kapena mutual inductance nthawi zambiri zimatchedwa kuti inductance coils. Nthawi zambiri amawonjezeredwa.Zomwe zimayambira za inductor zimaphatikizapo inductance, khalidwe lapamwamba, mphamvu yachibadwa, kukhazikika, masiku ano komanso nthawi zambiri zogwirira ntchito.Inductor yomwe imapangidwa ndi coil imodzi imatchedwa self-inductance, ndipo kudzipangira kwake kumatchedwanso kuti self-inductance coefficient.

Mutual Inductor

Pamene ma coil awiri a inductive ali pafupi wina ndi mzake, kusintha kwa maginito kwa coil imodzi yochititsa chidwi kumakhudza koyilo ina yochititsa chidwi, yomwe ndi yofanana. Kukula kwa inductance kumadalira kuchuluka kwa kulumikizana pakati pa kudzilowetsa kwa coil inductance ndi ma coil awiri a inductance. Zigawo zopangidwa pogwiritsa ntchito mfundoyi zimatchedwa mutual inductor.

Wotsutsa

Wotsutsa ndi gawo lamagetsi lamagetsi awiri opangidwa ndi zinthu zotsutsana, zomwe zimakhala ndi dongosolo linalake komanso malire omwe alipo panopa.

Choncho, resistor angagwiritsidwe ntchito ngati electrothermal chigawo chimodzi kutembenuza mphamvu magetsi mu mphamvu mkati mwa kukana ma elekitironi pakati pa maatomu.
Resistors amagawidwa kukhala zopinga zokhazikika, zopinga zosinthika komanso zopinga zapadera (makamaka kuphatikiza zotsutsa), zomwe zopinga zokhazikika zimagwiritsidwa ntchito kwambiri pazinthu zamagetsi.
Huizhou Mingda ali zaka 16 zinachitikira kupanga mitundu yonse ya inductors.

Ndife amodzi mwa akatswiri komanso otsogola opanga ma inductor ku China.

Takulandilani kuti mukambiranezambiri.
