Resistivity Ntawm Aluminium Ring

0.02825Ω·km
Qhov tsis kam ntawm Aluminium lub nplhaib yog 0. 02825252ωωωω at at at 20 20 degree. Resistivity yog ib qho tseem ceeb ntsuas ntsuas cov ntaub ntawv, uas qhia tau tus nqi tiv thaiv ib qho ntev thiab ib chav nyob hauv qab ntawm chav hluav taws xob. Aluminium yog ib tus neeg ua yeeb ncuab ib txwm muaj, thiab nws txoj kev tiv thaiv ncaj qha cuam tshuam cov kev ua tau zoo thiab kev ruaj khov ntawm lub zog kis. ‌

Zais Cov Lus Qhia
Lub resistivity ntawm lub nplhaib aluminium yog cuam tshuam los ntawm ntau yam:

Khoom purity: Qhov siab dua qhov purity ntawm txhuas sawb, tsawg impurities nyob rau hauv, qhov tsawg obstacles lub electrons ntsib thaum kis tau tus mob, thiab cov resistivity qis dua.
Qhov kub thiab txias: Cov nyhuv ntawm qhov kub ntawm qhov tsis kam ntawm lub nplhaib tawm ntawm lub nplhaib txhuas yog feem ntau tau cuam tshuam hauv cov thermal kev co ntawm cov hlau lattice. Raws li qhov kub nce, lub lattice thermal kev co ua kom tsis muaj zog, thiab cov tshuab hluav taws xob tau yooj yim dua thaum lub sijhawm kis, yog li nce qhov tsis kam.
Kev siv tswv yim
Nkag siab txog qhov kev tiv thaiv ntawm lub nplhaib aluminium yog qhov tseem ceeb heev rau kev xa xov hluav taws xob, xaiv cov khoom siv, thiab lwm yam. Nyob rau hauv cov txheej txheem ntawm kev xa hluav taws xob, xaiv cov khoom siv hluav taws xob tsim nyog tuaj yeem txo cov kab poob thiab txhim kho kev siv hluav taws xob. Raws li cov khoom siv hluav taws xob zoo heev, qhov kev tiv thaiv ntawm aluminium nplhaib yog ncaj qha cuam tshuam rau kev sib kis tau zoo. Tsis tas li ntawd, lub nplhaib aluminium kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv hluav taws xob xws li transformers thiab motors, thiab nws cov resistivity ncaj qha cuam tshuam rau kev ua haujlwm thiab kev ruaj ntseg ntawm cov khoom siv.
