Ceeb toom: Qhov kev tiv thaiv ntawm tus neeg xyuas pib tsuas yog nyob ntawm qhov tau hais los saum toj no peb yam xws li, ntev, thaj tsam ntawm ntu ntu, thiab qhov xwm txheej ntawm cov khoom ntawm tus neeg xyuas pib. Tsis tas li ntawd, nws tseem nyob ntawm lub cev xws li qhov kub thiab txias tab sis tsis muaj kev ywj pheej ntawm nws cov duab thiab qhov loj me.
Ntawm yam twg yog qhov kev tiv thaiv ntawm tus neeg xyuas pib nyob ntawm Chav 10?
Qhov kev tiv thaiv ntawm tus neeg xyuas pib nyob ntawm cov hauv qab no: Qhov kub ntawm tus neeg xyuas pib . Cov cheeb tsam hla ntawm tus neeg xyuas pib . Length of conductor.
Ntawm yam twg qhov kev tiv thaiv ntawm tus neeg xyuas pib tsis nyob ntawm?
Resistivity yog cov khoom vaj khoom tsev. Nws tsuas yog nyob ntawm cov khoom ntawm tus neeg xyuas pib. Nws tsis yog nyob ntawm cov duab thiab qhov loj ntawm tus neeg xyuas pib. Whereas qhov tsis kam yog nyob ntawm cov duab thiab qhov loj ntawm tus neeg xyuas pib.
Dab tsi yog yam cuam tshuam rau qhov kev tawm tsam ntawm tus neeg xyuas pib thiab ua li cas?
Qhov kev tiv thaiv ntawm cov khoom yog nyob ntawm ntawm nws qhov xwm txheej thiab qhov kub ntawm tus neeg xyuas pib, tab sis tsis nyob ntawm nws cov duab thiab qhov loj me. Ib tug zoo conductor muaj tsawg resistivity, whereas ib tug phem conductor los yog insulator muaj siab resistivity. Lub resistivity ntawm semi-conductors nyob nruab nrab ntawm cov conductors thiab insulators.
Dab tsi yog yam cuam tshuam rau hluav taws xob tiv thaiv?
Muaj plaub yam cuam tshuam rau kev tiv thaiv uas yog Kub, Ntev ntawm cov xaim, Cheeb Tsam ntawm ntu ntu ntawm cov xaim, thiab qhov xwm txheej ntawm cov khoom.
