Question Solved1 Answer i want all part of this question please  The circuit shown has the following parameters: \( \mathrm{R}=100 \mathrm{Ohm}, \mathrm{L}=12 \mathrm{mH} \) and \( \mathrm{C}=2 \mathrm{uF} \). 1. First analyze the circuit shown theoretically and determine which damping case it represent based on the inductor current (over damped, under damped or critical damped ?). (1) 2. Using Matlab Online (Simulink) recreate the circuit shown, simulate it and show the waveforms of the Source voltage (Scope-1), Capacitor voltage (Scope-2) and the inductor current (Scope-3) (simulation Stop Time \( =8 \mathrm{mS} \) ). As shown: \( \mathrm{R}=100 \mathrm{Ohm}, \mathrm{L}=12 \mathrm{mH} \) and \( \mathrm{C}=2 \mathrm{uF} \). (2) 3. Based on the simulation results, does the inductor and capacitor reach steady state before the end of each half cycle? If so, verify those steady state inductor current and capacitor voltage by calculating the cpacitor's steady state voltage and the inductor's steady state current by hand.(2) 4. Change the capacitor value to achieve the other two different types of damping and attach the new inductor's current waveforms from Scope-3. Verify the damping change using the theoretical analysis.
