伏安法测电阻时安培表采用内、外接法的判定条件

The criterion of connecting the ammeter inside or outside while using volt-ampere law to measure a resistance

导出了在物理实验中用伏安法测电阻时安培表采用内、外接法的判定条件,并在实验上给予了验证.

The criterion of connecting the ammeter inside or outside while using volt-ampere law to measure a resistance in physical experiment is introduced theoretically and varified experimentally.
