Exploration in Adjustment of AC Electric Bridge

Article Preview

Abstract:

One method called “low-order digit decided by high-order digit” is introduced to be applied to equilibrate AC electric bridge with two adjustable parameters frequently encountered in college physics experiment. The full verification of this method is discussed intuitionally. It is indicated that one can eliminate some disturbance of noise and improve measurement precision by using this method.
