The calculable resistors can be used to calculate AC-DC difference dependence of frequency. Usually the resistance wires are chosen high resistivity material and as thin as possible to avoid skin effect and so on. However, this kind of wires often induce much temperature drift from DC base value, when current flows through the wires. The performance of the calculable resistors is limited by the loading capability. The loading capability limited the using of calculable resistors in some area, leading to low stability of the AC-DC calculable difference. To solve this problem, a kind of coaxial calculable resistors design was proposed here to improving the calculable resistors and acquires good results in experiments.
