用研讨教学法进行RLC串联谐振实验教学

Carries on the RLC Series Resonance Experiment Teaching with the Deliberation Teaching Method

由于电阻器、电感器和电容器并非理想的电路元件,如果实验方法不当将造成较大的系统误差,使学生对RLC谐振理论与实验产生难解之惑。采用"研讨教学法",引领学生分析讨论RLC串联实验电路的谐振原理,确定减小系统误差的实验方法,使学生更好地通过实验研究RLC串联谐振特性,并探讨实验中电感和电容的特性,培养学生分析解决实际问题的能力,并领悟RLC串联谐振实验的物理思想。

Because resistors,inductors and capacitors are not ideal circuit elements,an inappropriate experimental method will result in a bigger systematic error to make students puzzled with P.LC resonance theory and experimental. The ＂discussion teaching＂ method is appropriate for this experiment teaching,which can lead students to analyze and discuss the experimental series RLC resonant circuit theory,and can determine a experiment method to reduce the system error. These can make students study RLC series resonance characteristics better through the experimental and explore the experimental inductor and capacitance characteristics,and can train students to analyze and solve practical problems and to understand better the physical ideas of RLC series resonance experiment.
