Question
## Figure 3.1: RLC Circuit Analysis

**Figure 3.1** shows an RLC circuit at time \( t > 0 \text{ s} \). Assume a current source of \( 5 \text{A} \) is applied to the circuit. The inductor has an initial current \( i_L(0) = 20 \text{ mA} \) and the initial capacitor voltage \( v_C(0) = 10 \text{ V} \).

![RLC Circuit Diagram](RLC_Circuit_Diagram.png)

- **Components:**
  - \( I_S \): Current source providing \( 5 \text{A} \)
  - \( i_L(t) \): Current through the inductor \( L \)
  - \( v_C(t) \): Voltage across the capacitor \( C \)
  - \( L \): Inductor with initial current \( i_L(0) = 20 \text{ mA} \)
  - \( C \): Capacitor with initial voltage \( v_C(0) = 10 \text{ V} \)
  - \( R \): Resistor

### Tasks

1. **Design the Circuit:**

   - Design your circuit to obtain an overdamped, critically damped, and underdamped response. 
   - For the design, choose the undamped frequency \( \omega \) in the range of \( 300 - 600 \text{ rad/s} \).
   - **Note:** Use a different \( \omega \) value for each group.

2. **Find Expressions:**

   (a) 
   - Find the expression of \( v_C(t) \) and \( i_L(t) \) for \( t \geq 0 \text{ s} \) for each of your circuit designs from part Q1(a).
   - Show all calculations.

**Figure Q1** outlines these tasks and provides detailed descriptions for each step required to design, analyze, and solve the circuit configurations for different damping scenarios.
