Raws li ib qho tseem ceeb ntawm cov khoom siv hluav taws xob, lub tshuab hloov pauv ua lub luag haujlwm dav thiab tseem ceeb thoob plaws ntau yam kev lag luam thiab ntau yam ntawm cov neeg niaj hnub no.
Lub transformer yog ib qho khoom siv hluav taws xob uas siv lub hauv paus ntsiab lus ntawm electromagnetic induction los hloov alternating tam sim no (AC) voltage. Nws yog dav siv nyob rau hauv lub hwj chim systems, industrial ntau lawm, thiab lub neej txhua hnub. Nws lub luag haujlwm tseem ceeb yog kev hloov pauv hluav taws xob; Tsis tas li ntawd, nws ua haujlwm rau lub hom phiaj xws li kev hloov pauv tam sim no thiab kev sib piv impedance.
Transformers ua lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam thiab ua ib qho tseem ceeb ntawm cov tshuab hluav taws xob.
