| 摘 要： | 利用电压法、李萨茹图形法和双轨迹法分别测量了RC串联电路的相移,并将实验值与理论值进行了比较。研究表明,在所选择的频率波段内,这三种方法测量的实验值与理论值符合的很好,具有高精度、测量装置简单、操作方便等优点。通过对以上三种测量方法的研究,能够让学生从直观上更深入地理解对RC串联电路的特性。

The Study of the Measuring Methods for Phase Shift in the RC Series Circuit |
| |
| Abstract: | The phase shift in the RC series circuit was measured using voltage method,Lissajous-figure method and double-track method respectively in this paper,and the experimental values were compared with the theo-retical values.The results shows that the experimental values obtained from these methods are in good with the theoretical ones,and these three measuring methods have high precision,simple measuring devices,low detec-tion limits,easy to operate,and other advantages.Based on the study of the above three measuring methods,we can let the students have a deeper understanding intuitively the characteristics of the RC series circuit. |
