| Abstract: | This paper introduced the way to measure the internal resistance of the standard cell by using sensitive galvanometer as the indicator when two standard cells of the same model were reversely connected.Errors caused by the insufficient sensitivity of the current circuit were analyzed in detail,and some suggestions were presented on how to improve the measuring accuracy. |
