摘要
介绍了一种改进的惠斯通电桥电路,用于测量高值电阻的阻值。文中通过对实验误差、灵敏度的理论计算讨论了实验条件和测量范围。该实验可作为大学物理实验课程中"电桥法测电阻专题实验"的扩充。
It introduces an improved Wheatstone bridge,used lor measuring high resistance （ ≥1MW）.Based on the theoretical calculation of experimental error and sensitivity ,this paper discusses the experimental condi-tions and the measuring range.This experiment can be added to ＂ bridge method in measuring resistance＂ in the Physics Experiment Course.
