| 摘 要： | 主要研究如何精确地测量电流在金属导线中的传输速度。根据速度等于长度除以时间的原理,讨论了如何通过测量电流流过导线的时间的方法来测量电流速度;同时提出了减小测量误差的方法。通过软件仿真及实验测试,测得电流在导线中的传输速度大约是297619 km/s,比光速略小。该方法原理简单,测量结果比较准确。

| Abstract: | The paper studies how to measure electric current velocity in metal wire accurately.On the principle of velocity being equal to length divided by time,this paper discusses the methods measuring electric current velocity by measuring the time interval.Also this paper proposes some ways of decreasing errors.Through simulation and experiment,we can get the electric current velocity is about 297 619 km/s,which is less than the velocity of light.This experiment shows that the method is simple and the result is a... |
