Transformer (Lus Askiv lub npe): [trAns'fC:mE(r), tra:-].
Transformer yog ib qho khoom siv hloov pauv tam sim no (AC) voltage, tam sim no, thiab impedance. Thaum AC tam sim no ntws los ntawm thawj kauj, AC magnetic flux yog tsim nyob rau hauv cov tub ntxhais hlau (los yog hlau nplaum), inducing ib voltage (los yog tam sim no) nyob rau hauv lub thib ob kauj. Lub transformer muaj ib tug hlau core (los yog magnetic core) thiab coils. Cov coils muaj ob los yog ntau dua windings; lub winding txuas nrog lub zog hluav taws xob yog hu ua thawj kauj, thiab qhov seem windings yog hu ua cov coils thib ob.
Lub transformer yog ib qho khoom siv hluav taws xob thiab khoom siv hluav taws xob. Nws tuaj yeem siv los hloov pauv qhov hluav taws xob hloov pauv ntawm qee tus nqi rau qhov hloov pauv ntawm lwm tus nqi nrog tib zaus. Nws tseem tuaj yeem hloov pauv tus nqi ntawm kev hloov pauv tam sim no, hloov pauv impedance, hloov theem, lossis hloov zaus.
