| 摘 要： | "电感和电容对交变电流的影响"演示实验的操作难度大且现象不明显,为此介绍了2种演示该实验的方法,一是通过将电灯分别与电感(电容)和电阻串联对比进行实验来演示电感和电容对交变电流的影响;二是通过信号发生器和示波器来研究交流电对电感(电容)的影响.2种方法演示效果均较好.

| Abstract: | The demonstration experiment of effect of inductance and capacitance on alternating current is difficult to manipulate and the phenomenon is unconspicuous. In this work, two demonstra- tion methods are introduced. One is to connect light bulbs with inductance and capacitance respectively, by comparing the brightness of the bulbs to demonstrate the influence to alternating current. The other is to use signal generator and oscillograph to demonstrate the influence to alternating current. The demonstration effect of both methods are preferable. |
