【Abstract】 Systematical errors often happen in the result of measurement because of the internal resistance of the electric meter when it is used for measurement. The principle of compensation of potential difference is applied to compensate the galvanometer and voltmeter in order to get rid of the influence of the internal resistance on the result of measurement.更多还原
