Yog li tooj liab yog a lattice ntawm zoo tooj liab ions nrog dawb electrons txav ntawm lawv. … Cov electrons tuaj yeem txav mus los ntawm cov hlau. Vim li no, lawv hu ua dawb electrons. Lawv kuj tseem hu ua conduction electrons, vim tias lawv pab tooj liab los ua ib qho zoo conductor ntawm tshav kub thiab hluav taws xob.
Vim li cas tooj liab yog tus conductor zoo dua hlau?
tooj liab muaj qhov qis duathiab yog tus coj hluav taws xob zoo dua li hlau. … tooj liab yog ib tug zoo conductor tshaj hlau, uas txhais tau hais tias tam sim no yuav ntws yooj yim dua (nrog tsawg kuj) los ntawm tooj.
Puas yog tooj liab yog tus coj zoo heev?
Thaum txhim kho kom raug, nws yog cov hlau zoo tshaj plaws thiab ua tau zoo tshaj plaws los tsim hluav taws xob. Copper feem ntau yog siv los ua tus coj zoo hauv cov khoom siv hauv tsev thiab hauv cov khoom siv hluav taws xob feem ntau. Vim nws tus nqi qis, feem ntau cov xov hlau yog tooj liab-plated.
