摘要
在RLC串联电路暂态研究的实验中,由于电路中存在一定的系统电容,使得阻尼振荡周期和临界阻尼电阻的实验值与理论值存在一定的偏差。本论文用两种方法对系统电容进行了估算,并对阻尼振荡周期和临界阻尼电阻的理论值进行修正,从而减小与实验值的相对误差。
In the experiment of transient study of RLC series circuit,the experimental value of damped oscillation period and critical damped resistance is deviated from the theoretical value for the existence of certain system capacitance in the circuit.The system capacitance is estimated by two methods,and the theoretical values of damped oscillation period and critical damped resistance are corrected to reduce the relative error with the experimental values.
