| Abstract: | In this paper,the experimental method was applied to study the effect of potentiometer on the sensitivity of potential difference meter.The results indicate that the measured potential is in good agreement with the value of dry battery when the sensitivity is taken ten and the ratio of divided voltage of potentiometer was kept ten.This provides a guide for the design of experiment and choice of resistance of potentiometer. |
