### Question 1 of 2

The switch has been closed for a long time. It opens at t=0.

#### i) Find \( i_L(0^+) \) and \( v_c(0^+) \) (Hint: Do Analysis before t=0)
**Box Answers:**
\[ i_L(0^+) = \]
\[ v_c(0^+) = \]

#### ii) For \( t > 0 \), what kind of system response does the series RLC circuit produce for \( i_L(t) \)? (Underdamped, overdamped, critically damped). 

Hint: Draw circuit after \( t > 0 \), find \(\alpha\), \(\omega\). Represent form of \( i_L(t) \) based on system response.

**Box Answers:**

#### iii) Find \(\frac{di_L(0^+)}{dt}\) and \(\frac{dv_c(0^+)}{dt}\)
**Box Answers:**
\[ \frac{di_L(0^+)}{dt} = \]
\[ \frac{dv_c(0^+)}{dt} = \]

### Question 1b
Assume (Given parameters for a new circuit to avoid carrying mistakes from previous analysis) you are told that a series RLC circuit is given and has an overdamped system response, with \( s_1 = -1 \), \( s_2 = -2 \), \( v_c(0^+)=1V \), \(\frac{dv_c(0^+)}{dt} = 2 \). Find \( v_c(t) \) for t > 0.
Hint: Solve for \( A_1 \), \( A_2 \) and represent \( v_c(t) \) correctly.

**Box Answer:**

---

### Diagram Explanation:
The schematic diagram provided shows a series RLC circuit consisting of:
- A 10V DC voltage source
- A switch that has been closed for a long time and opens at \( t = 0 \)
- A resistor (\(4\Omega\)) in series with an inductor (\(0.5H\)), another resistor (\(6\Omega\)), and a capacitor (\(0.02F\))

##### Key Circuit Elements:
- Resistor: \( 4\Omega \)
- Resistor: \( 6\Omega \
