摘　　要：电阻是电学中很重要的物理量,而在电学实验中,对结果的影响,导线电阻起着至关重要的作用。电磁测量是测量技术的一个重要组成部分,它包括了对电流、电压、电阻、电感、及其它各种电磁量的测量。实验是修正错误的依据和发展起点。文中针对电学实验中导线连接对实验结果产生较大误差,列举三个典型电路进行讨论和分析,并提出解决方案。Resistance is an important physical quantity in electricity,and in electricity experiment,wire resistance plays a most important role in the influence on result.Electromagnetic measurement is the most important part of measuring technologies,including measurement of electrical current,voltage,resistance,inductance,electric capacity and other electromagnetic volume.Experiment is the basis of correcting mistakes and the starting point of development.This paper analyses the major error is caused by the wire connection in electrical experiment.We discuss and analyse this problem in three typical circuits,and put forward the solution.
