**Problem 4: Analysis of the RC Circuit**

**Objective:**
Calculate \( v(t) \) and \( i(t) \) in the given circuit.

**Circuit Description:**

The circuit consists of the following components arranged as follows:

1. **Voltage Source:** A 24 V DC source.
2. **Resistors:** 
   - \( 4 \, \Omega \) resistor in series with the voltage source.
   - \( 1 \, \Omega \) resistor in parallel with the capacitor.
3. **Inductor:**
   - \( 1 \, \text{H} \) inductor in series with the \( 4 \, \Omega \) resistor.
4. **Capacitor:**
   - \( 0.25 \, \text{F} \) capacitor in parallel with the \( 1 \, \Omega \) resistor. 
5. **Switch:**
   - Initially open, closes at \( t = 0 \).

**Currents and Voltages:**

- \( i \) represents the current flowing through the inductor.
- \( v(t) \) is the voltage across the capacitor and the \( 1 \, \Omega \) resistor.

**Analysis Task:**

- Determine the expressions for \( v(t) \) (voltage across the capacitor) and \( i(t) \) (current through the inductor) for \( t \geq 0 \). 

The task involves analyzing the transient response of the circuit when the switch closes at \( t = 0 \). The analysis may involve solving differential equations derived from Kirchhoff's laws and taking initial conditions into account.
