If the circuit is composed of three ideal components: R, L, and C in series, the equivalent complex impedance of the circuit is given by Z=R+j(ωL-1/ωC). When ωL=1/ωC, that is, ω0=1/√LC, the equivalent complex impedance Z=R becomes purely resistive, and the voltage and current at the port are in phase. This phenomenon is referred to … Read more
This article demonstrates how to perform circuit simulation using MATLAB to measure the voltage of an RLC circuit. I am using R2014a, and the interface may vary slightly in different versions of the software. Open the MATLAB software and create a new Simulink Model, as shown in the figure below. After the untitled window pops … Read more
Virtual simulation experiments are an important direction in the reform of physics experimental teaching. Since their official use in university physics laboratory courses in the 1990s, they have greatly promoted the development of physics laboratory teaching across the country. However, as the reform of experimental teaching deepens and the demand for university physics laboratory teaching … Read more
