Resistivity ntawm aluminium pas nrig

Qhov tsis kam ntawm Aluminium Rods feem ntau yog ntawm 2.65 â {^ {{{{{} 10 ^ {{{{. Tus nqi tshwj xeeb yog cuam tshuam los ntawm ntau yam xws li lub purity, ntsuas kub thiab qauv ntawm txhuas. Tsis tas li ntawd, kev tiv thaiv ntawm txhuas ntau zuj zus nrog qhov kub thiab txias, yog li cov nyhuv ntawm kev hloov pauv kub thiab txias ntawm kev xav tau hauv kev siv. ‌

Lub resistivity ntawm txhuas muaj qee qhov zoo piv rau lwm yam hlau xws li tooj liab thiab hlau. Ntawm 20 degree, qhov resistivity ntawm tooj liab yog 1.75 × 10 ^ -8 Ω·m, ntawm txhuas yog 2.83 × 10 ^ -8 Ω·m, thiab cov hlau yog 9.78 × 10^{{ 12} Ω·m. Cov ntaub ntawv no qhia tau tias txhuas ua hluav taws xob zoo dua hlau tab sis me ntsis phem dua tooj liab.

Raws li ib lub teeb yuag hlau, txhuas muaj hluav taws xob zoo thiab kho hluav taws xob tsis kam thiab yog siv dav hauv kev tsim kho, tshuab siv hluav taws xob, tshuab thiab lwm daim teb. Tshwj xeeb tshaj yog qhov kev poob phaus thiab txo tus nqi txo, txhuas muaj qhov zoo tseem ceeb.
