A method of measuring low resistance
Measuring low resistance voltammetry, in order to obtain greater resistance to be measured by the voltage drop, current resistance to be measured should be large enough and with low range potential difference meter instead of the voltmeter can reach certain measurement accuracy.
When measuring low resistance with double bridge, the value of resistance of bridge arm should be as large as possible within the condition permission method, and the precision of bridge arm resistance should be as high as possible. A low resistance is measured by a double bridge, regardless of whether the voltage is connected internally or externally, and the resistance measurement is constant.
Voltammetry, double bridge method and double "single bridge" method can be used to measure low resistance. The measurement results of several methods are in good agreement.
