### Problem Description:

After a long time, the switch \( S_2 \) is opened and the switch \( S_1 \) is closed at \( t = 0 \).

1. **Find \( v(0) \).**
2. **Find \( v(t) \) for \( t > 0 \).**
3. **Find the instantaneous power dissipated by the circuit for all \( t > 0 \).**

### Circuit Diagram:

- **Components:**
  - **Voltage Source:** 30 V
  - **Resistors:**
    - \( 12 \, \Omega \) connected to the voltage source
    - Two \( 6 \, \Omega \) resistors in parallel to the \( 100 \, \text{mF} \) capacitor
    - \( 3 \, \Omega \) resistor in series with the \( 6 \, \Omega \) resistors
  - **Current Source:** 4 A
  - **Capacitor:** \( 100 \, \text{mF} \) (Millifarads)

- **Switches:**
  - \( S_1 \): Initially open, closes at \( t = 0 \)
  - \( S_2 \): Initially closed, opens at \( t = 0 \)

- **Connections:**
  - The \( 30 \, \text{V} \) source is connected to the first \( 12 \, \Omega \) resistor, followed by switch \( S_1 \).
  - The \( 100 \, \text{mF} \) capacitor is between the two parallel \( 6 \, \Omega \) resistors.
  - The \( 3 \, \Omega \) resistor connects in series to the \( 4 \, \text{A} \) current source.

This setup describes the initial and transient behaviors of a simple RLC circuit as switches alter the circuit configuration at time \( t = 0 \).
