RLC串联谐振实验中电源内阻的影响及实验方法探讨

Research on the Influence of the Internal Resistance of the Power Supply and the Experimental Methods of RLC Series Resonance Circuit

在RLC串联谐振实验中,信号发生器的内阻会对电源输出电压产生较大影响。如果在实验中测出电源的实际输出电压并应用该电压进行数据计算,也能得到满意的实验结果。

In the experiment of RLC series resonance circuit,the resistance of the signal generator has a great impact on the output voltage. The signal amplitude of the signal generator needs to be adjusted to keep the output voltage constant at each experiment frequency. If so,the repeated regulation is very tedious. The study shows that if the actual output voltage values of the power are measured and the result is used for data processing,the experiment can also be obtained.
