Txhawm rau xam qhov tam sim no nyob rau hauv ob kauj ruam thaum lub transformer khiav ntawm lub zog tag nrho, peb yuav tsum paub qee qhov tseem ceeb: lub peev xwm (los yog lub zog) ntawm lubtransformer, thiab cov voltages nyob rau hauv thawj thiab theem nrab coils. Raws li cov ntaub ntawv no, peb tuaj yeem daws qhov teeb meem siv lub zog sib npaug P=IV (lub zog sib npaug ntawm lub sijhawm tam sim no).
Ua ntej, cia peb xav tias lub peev xwm ntawm qhov hloov pauv yog S (hauv VA), qhov hluav taws xob hauv thawj kauj yog V1 (hauv volts), thiab qhov hluav taws xob hauv theem nrab yog V2 (hauv volts). Peb xav nrhiav tam sim no I2 (hauv amperes) nyob rau hauv lub kauj thib ob.
Rau kev ua haujlwm puv fais fab, lub zog hauv lub hauv paus thiab theem nrab coils ntawm transformer yuav tsum sib npaug.
Yog li ntawd, peb muaj qhov sib npaug hauv qab no:
P_Primary=P_Secondary
V1 × I1 = V2 × I2
Vim muaj kev ua haujlwm puv fais fab, peb xav tias tam sim no I1 nyob rau hauv thawj kauj yog txiav txim siab los ntawm lub peev xwm S ntawm transformer thiab voltage V1 nyob rau hauv thawj kauj, piv txwv li:
I1 = S / V1
Tam sim no peb tuaj yeem siv cov ntaub ntawv no txhawm rau nrhiav I2 tam sim no hauv cov coil thib ob:
I2 = (S / V1) × (V2 / V1)
= S × (V2 / V1^2)
Yog li, paub txog lub peev xwm ntawm transformer S, qhov voltage ntawm thawj kauj V1 thiab qhov voltage ntawm theem nrab kauj V2, peb tuaj yeem xam qhov tam sim no I2 nyob rau hauv lub kauj thib ob siv cov qauv saum toj no.
Nws yuav tsum raug sau tseg tias qhov kev suav no yog raws li qhov kev xav ntawm qhov zoo tagnrho transformer, piv txwv li, tsis muaj zog poob. Nyob rau hauv kev xyaum, lub xam tam sim no yuav tsum tau muab multiplied los ntawm ib tug efficiency vim muaj lub zog poob thiab efficiency ntawm transformer.
