#### Circuit Description:
The given circuit is a combination of resistors and inductors connected to a DC voltage source. The objective is to find the current \( I_x(t) \) through a specific branch for \( t \geq 0 \).
**Components:**
- A 9.6 V DC voltage source.
- A 6 kΩ resistor.
- A 4 kΩ resistor.
- A 12 kΩ resistor.
- An inductor with inductance 1.2 H.
- An inductor with inductance 360 mH.
- A switch that closes at \( t = 0 \).
**Configuration:**
- The first branch of the circuit contains a 6 kΩ resistor in series with a 1.2 H inductor.
- The middle branch consists of a 4 kΩ resistor in series with a 9.6 V voltage source and a switch (which closes at \( t = 0 \)).
- The third branch contains a 12 kΩ resistor in series with a 360 mH inductor.
- The current \( I_x(t) \) flows through the branch containing the 12 kΩ resistor and 360 mH inductor.
When the switch is closed at \( t = 0 \), we need to analyze the resulting circuit to determine the behavior of current \( I_x(t) \).
### Step-by-Step Solution:
To solve for \( I_x(t) \):
1. **Initial Conditions:**
- Determine the initial current through the inductors and the initial voltages across the resistors and inductors right before the switch is closed at \( t = 0 \).
2. **Formulate the Differential Equation:**
- Using Kirchhoff's laws (both voltage and current), formulate the differential equation governing the circuit.
3. **Solve the Differential Equation:**
- Solve the differential equation with appropriate boundary conditions.
4. **Analyze the Steady-State and Transient Responses:**
- Combine the solutions for the transient response (natural solution) and the steady-state response (particular solution) to find the complete solution for \( I_x(t) \).
