Dab tsi yog vim li cas vim li cas lub multimeter tsis tuaj yeem ntsuas tus nqi tiv thaiv thaum ntsuas qhov 5-xim nplhaib tsis kam?
Ntawm tsib-xim nplhaib resistor, thawj 3 tus lej yog tus nqi zoo, tus lej thib plaub yog ntau yam, thiab tus lej kawg yog qhov yuam kev. Cov xim sib lawv liag ntawm cov resistor yog dub 0, xim av 1, liab 2, txiv kab ntxwv 3, daj 4, ntsuab 5, xiav. 6, ntshav 7, grey 8, dawb 9, kub 10 minus 1 lub zog, nyiaj 10 rho tawm 2 lub zog, tsis muaj xim.
Piv txwv li daj txiv kab ntxwv xiav xim av kub=436*10=4360 ohms, qhov yuam kev yog "ntxiv lossis rho tawm 5 feem pua" thiab tom qab ntawd siv multimeter los ntsuas, yog tias nws nyob hauv thaj tsam li qub ntawm tus nqi no, qhov kev tiv thaiv yog qhov zoo, yog tias nws tshaj qhov ntau, nws yuav yog Resistors yuav deteriorated.
Yog tias tsis muaj tus nqi tiv thaiv, ces tus resistor yog qhib Circuit Court. Ntawm qhov tsis sib xws, lub multimeter tuaj yeem tawg, thov hloov nws nrog lub multimeter tshiab los ntsuas nws.
