Resistivity thiab conductivity

Ib tus neeg saib xyuas ib ntus nrog ib ncua l thiab ib qho chaw hla ntawm S, nrog lub voltage v thov rau ob xaus, yuav muaj qhov ntws tawm tam sim no, uas yog hu ua conductivity.

Raws li Ohm txoj cai, R tsis tsuas yog cuam tshuam nrog cov khoom ntawm cov khoom siv, tab sis kuj mus rau qhov ntev l thiab hla ntu ntawm cov khoom. Cov khoom tawm tsam tus nqi ntawm cov khoom ntawm cov khoom ntawm cov khoom nws tus kheej thiab tuaj yeem siv los ua kom pom kev ua haujlwm ntawm cov khoom. Raws li cov sib txawv tiv thaiv, cov ntaub ntawv tuaj yeem faib ua cov neeg ua haujlwm, cov tswj tau thiab semiconductors. Qhov tsis kam ntawm tus neeg saib xyuas yog tsawg dua {, ω} {, resist resist resist resistond of s snonductors yog}}}}}}} ·
