| Abstract: | Potentiometer has high accuracy and sensitivity due to the unique design of the potential compensation to avoid errors arising from internal resistance of the power.In this article,AC power was designed to improve UJ36a DC power potentiometer and was used to measure the temperature coefficient of low resistance and I-V characteristics of the diode,which are consistent with the theoretical value and the potentiometer performance was stable. |
