RLC电路谐振曲线的测绘在普通物理实验中一般采用测点描线的方法,其实验线路如图1所示,分别测出各分立频率点对应的电阻R上的电压值,然后描点作图,作出谐振曲线。这种方法测量速度慢,作出的曲线准确性差,笔者增加一台x-y单笔函数记录仪 Resonance curve of RLC circuit mapping In general physics experiments commonly used method of measuring lines, the experimental circuit shown in Figure 1, were measured at each discrete frequency point corresponding to the resistance of the voltage on the R, and then traced plotted to make Resonance curve. This method of measurement is slow, the accuracy of the curve made poor, I added a x-y single-function recorder
