Abstract: Inductance (L),capacitanee (C),and resistanee (R) serve as fundamental passive components incirevit design,and the precise measuremnent of their paramelers is crucial for cirevuit design, signal processing,and system stability analysis,'This paper proposes an LCR measurement scheme based on the vector comparisonmethod , utilizing common laboratory equipment such as oscilloscopes and signal generators to obtain complexvolage values containing phase information, from which the numerical values of LCR parameters are furthercaleulated,.The inlluence of lead resistance on the experiment is eliminated through the Kelvin four-terminalcomnection method. This design scheme is suitable for experimental teaching and engineering preliminaryresearch scenarios.
