Question

68 An RLC circuit with a parallel bypass resistor (Problems 3.10 and 5.11) is shown in Fig. P6.8. At time t 0 the circuit has zero current in both loops and the capacitor C has a stored charge of 0.01 C. The system parameters are R1 0.4 Ω, R2-020, Cz 0.04 F, and L-0.01 H. Use Simulink to obtain the system response where the source voltage is a sinusoidal function, em) 05 sin 10t V. A voltmeter is used to measure the voltage across the capacitor C. Plot Simulink's prediction of the voltmeter output for a simulation time of 1.5s. R2 tn Figure P6.8
