Qhov kev tawm tsam ntawm tus neeg xyuas pib nyob ntawm thaj tsam ntawm tus neeg xyuas pib, qhov ntev ntawm tus neeg xyuas pib, thiab nws qhov kev tiv thaiv. Nws yog ib qho tseem ceeb kom nco ntsoov tias hluav taws xob conductivity thiab resistivity yog inversely proportional, txhais tau hais tias qhov ntau conductive ib yam dab tsi yog qhov tsawg resistive nws yog.
Dab tsi yog 4 yam cuam tshuam rau qhov tsis kam ntawm tus neeg xyuas pib?
Muaj 4 yam sib txawv uas cuam tshuam rau kev tiv thaiv:
- hom khoom ntawm cov khoom siv hluav taws xob ua.
- Qhov ntev ntawm qhov resistor.
- Lub thickness ntawm cov resistor.
- Qhov kub ntawm tus neeg xyuas pib.
Ntawm dab tsi yog qhov kev tiv thaiv ntawm tus neeg xyuas pib nyob ntawm Ncert?
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 dab tsi uas qhov kev tiv thaiv ntawm tus neeg xyuas pib tsis nyob ntawm?
Nws nyob ntawm cov khoom siv ntawm tus neeg xyuas pib xwb. Nws tsis yog nyob ntawm tus 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.
Ntawm yam twg qhov kev tiv thaiv ntawm tus neeg xyuas pib nyob ntawm muab nws cov lus qhia lej?
qhov tsis kam yog nyob ntawm qhov kev tiv thaiv ntawm cov khoom, qhov ntev, qhov kub, thiab thaj tsam ntawmntu ntu. Kev ua lej, R=pl/A qhov twg p yog qhov kev tawm tsam, l yog qhov ntev thiab A yog thaj tsam ntawm ntu ntu. los saum toj no, p=RA/l=ohmm2/m=ohm-meter.
