Qeexida iyo Shaqada Aasaasiga ah

Inductor waa qayb elektaroonik ah oo aan fiicneyn oo kaydisa tamarta qaab goob birlab ah marka uu korontadu dhex socoto. Waxay caadi ahaan ka samaysan tahay gariiradda xadhigga boogta ee ku wareegsan xudunta, taas oo noqon karta hawo, bir, ama ferrite. Shaqada aasaasiga ah ee inductor waa ka soo horjeedka isbeddelada hadda jira, hantida loo yaqaan inductance, oo lagu cabbiro henries (H).

Inductors waxay aasaas u yihiin wareegyada meesha kaydinta tamarta, shaandhaynta, ama habaynta calaamadaha loo baahan yahay. Inta badan waxaa loo isticmaalaa iyadoo lala kaashanayo capacitors iyo resistors si loo abuuro filtarrada, oscillators, iyo transformers. Tusaale ahaan, sahayda korantada, inductors waxay kaa caawinaysaa in ay damiso isbedbedelka korantada, iyaga oo hubinaya hawlgal xasiloon.

Fahamka aasaasyadan ayaa lama huraan u ah in la fahmo sida inductors ay ugu shaqeeyaan wareegyada dhabta ah.

Sida Inductors u kaydiyaan tamarta

Inductors waxay tamarta ku kaydiyaan goobahooda magnetic marka hadda uu dhex socdo. Habkani wuxuu ku yimaadaa sababtoo ah Sharciga Farday ee Induction, kaas oo sheegaya in goobta magnetka ee isbeddelaya ay keento koronto ku jirta kirishbooyada. Marka hadda uu kordho, goobta birlabku way sii fidaysaa, kaydinta tamarta. Taa beddelkeeda, marka hadda uu hoos u dhaco, goobta birlabku waa dumaa, taasoo sii deynaysa tamarta kaydsan oo dib ugu soo celisa wareegga.

Qadarka tamarta lagu kaydiyo inductor waxaa lagu xisaabin karaa iyada oo la adeegsanayo caanaha:

[ E = \ frac {1}{2} LI^2 ]

Halkee:

• ( E ) = Tamarta lagu kaydiyo (ku jirta joules)
• (L) = Inductance (in henries)
• (I) = Hadda (amperes)

Awoodda kaydinta tamarta ayaa ka dhigaysa inductors kuwo qiimo leh codsiyada sida sahayda korantada, halkaas oo ay ka caawiyaan ilaalinta heerarka korantada ee joogtada ah in kasta oo isbeddellada hadda jira. Hoos waxaa ku yaal isbarbardhigga kaydinta tamarta ee inductors iyo capacitors:

Awoodda goobtani waxay kuxirantahay tirada wareegyada gariiradda, walxaha xudunta u ah (haddii ay jiraan), iyo hadda laftiisa. Haddii uu hadda isbeddelo, goobta birlabku sidoo kale waa is beddelaa, taasoo keenta danab ka soo horjeeda isbeddelka hadda. Dhacdadan waxaa loo yaqaanis-abuuridwaxaana lagu cabbiraahenries (H).
