| Abstract: | Using the thinking of half deviation in the physics experiment of middle school, the ammeter internal resistance is measured. Through parallel and series resistor to the ammeter,the series and par- allel resistance is regulated to make the ammeter pointer achieve full partial and semi-partial, then the ammeter internal resistance can be measured, which expands the method of measuring the ammeter in- ternal resistance. |
