**Problem Statement:**
For the given RLC circuit, the switch is initially in the open position and closes at time t = 0. Consider R = 15 kΩ, L = 500 mH, C = 10 nF, Is = 5 mA. Write down necessary circuit equations and answer the following questions. Show necessary steps and supporting work to receive full credit.
**Questions:**
a) Derive the s domain expression for voltage across and current through the capacitor for t ≥ 0.
b) Derive the time domain expression for voltage across and current through the capacitor for t ≥ 0.
c) Calculate the initial and final values for voltage across and current through the capacitor.
**Circuit Diagram Explanation:**
The diagram depicts a series RLC circuit with the following components:
- A current source \( I_s \) of 5 mA.
- A resistor \( R \) with a value of 15 kΩ.
- An inductor \( L \) with a value of 500 mH.
- A capacitor \( C \) with a value of 10 nF.
- Initially open switch that closes at \( t = 0 \).
Labelled quantities in the circuit include:
- \( V_R \) represents the voltage across the resistor.
- \( V_L \) represents the voltage across the inductor.
- \( V_C \) represents the voltage across the capacitor.
- \( I_R \) represents the current through the resistor.
- \( I_C \) represents the current through the capacitor.
- \( I_L \) represents the current through the inductor.
When the switch closes at \( t = 0 \), the analysis of the resulting transients can be carried out in both the s-domain (Laplace domain) and the time domain.
---
**Detailed Analysis:**
1. **s-domain Analysis (Laplace Transform):**
- Utilize Kirchhoff’s Voltage Law (KVL) and Laplace transforms to establish the s-domain circuit equation.
- Solve for \( V_C(s) \) and \( I_C(s) \).
2. **Time-domain Analysis:**
- Apply the inverse Laplace transform to the s-domain solutions.
- Derive expressions for \( v_C(t) \) and \( i_C(t) \) for \( t ≥ 0 \).
3. **Initial and Final
