摘要
RLC串联谐振电路实验是《大学物理实验》中的一个重要内容。一般教材采取通过测量电阻两端电压的谐振曲线来确定谐振频率,但发现此时U_r/U通常小于1,从而会感到疑惑。本论文分别从实验和理论的角度验证了通过测量电感和电容两端电压的谐振曲线来确定谐振频率的可行性。
The experiment of RLC series resonant circuit is an important content of College Physics Experiment.The resonance frequency is determined by measuring the resonance curve of the voltage for the resistor in the textbooks.However,it is found that the value of U r/U is usually less than 1,which may lead to doubts for students.The feasibility of determining the resonant frequency by measuring the resonant curves of the inductance and the capacitor is verified through experiment and theory,respectively.
