Txoj Cai ntawm Transformer
Lub transformer yog ib qho cuab yeej siv lub hauv paus ntsiab lus ntawm electromagnetic induction los hloov AC voltage. Lub ntsiab Cheebtsam yog thawj kauj, theem nrab kauj thiab hlau core (magnetic core). Hauv cov khoom siv hluav taws xob thiab hluav taws xob hluav taws xob, nws feem ntau yog siv rau qhov hluav taws xob nce thiab poob, impedance txuam, thiab kev sib cais kev nyab xeeb. Nyob rau hauv lub tshuab hluav taws xob, txawm tias lub kauj txav los ntawm qhov chaw sib nqus los yog qhov chaw sib nqus txav los ntawm lub kauj ruaj khov, lub peev xwm hluav taws xob tuaj yeem ua rau hauv lub kauj. Nyob rau hauv ob qho tib si, tus nqi ntawm magnetic flux tseem zoo ib yam, tab sis tus nqi ntawm magnetic flux intersecting nrog lub coil hloov. Qhov no yog lub hauv paus ntsiab lus ntawm kev sib nrig sib induction. Transformer yog ib qho cuab yeej siv hluav taws xob sib nqus induction los hloov voltage, tam sim no thiab impedance
