Abstract
Current dependence and stability of the measured resistance value are very important for the accurate measurement of DC standard resistor.In this paper,the volt-ampere (V-I)measurement method has been applied to study the current depend-ence of four different types of standard resistors.Diverse values are obtained through the investigation of their stability at dif-ferent currents.Therefore,the current dependence coefficient (CDC)can be determined for each one of the studied resistors. Research shows CDC depends on the applied current value,the measurement time and the resistor type,as clearly demonstra-ted in this research.关键词
