| Abstract: | In physical experiments the stability of power affects directly the accuracy of measurement.But under the high accruacy of power will the accuracy of measurement increase if power voltage is increased properly?Will if be that the lower the inner resistance is the more accurate the measurement will be? In this paper some investigations concerning the specific problems in the experiment are conducted. |

| Keywords: | stability power voltage sensibility inner resistance |
