Dab tsi yog vim li cas vim li cas lub multimeter ntsuas tsib-xim nplhaib tsis kam thiab qhia tau hais tias tus nqi tiv thaiv yog infinite
Lub tsib-xim nplhaib kuj qhia tau hais tias tus nqi kuj yog infinite
Thaum siv ib lub multimeter los ntsuas tsib-xim lub nplhaib tsis kam, qhov tso tawm qhov kev tiv thaiv tus nqi yog infinite. Cov laj thawj tshwm sim yog raws li hauv qab no:
1. The resistance is a high-resistance resistance of tens of MΩ or more. General digital multimeters can only measure resistances below 20MΩ. If the measured resistance exceeds the maximum measurement range of the multimeter, the multimeter will display "1" (ie overflow). You can first check whether the fourth color ring of the resistor is green or blue to confirm whether the resistor is a high-resistance resistor.
2. Yog hais tias cov zaj duab xis conductive ntawm qhov kev ntsuam xyuas resistor puas nyob rau hauv qhib Circuit Court, tus nqi kuj yuav ntsuas tsis tau, thiab tej zaum kuj tso saib tus nqi yog infinite.
