Question

### Electrical Circuit Analysis

**Problem Statement:**

For \( t < 2 \, \text{s} \), the switch is closed, and you may assume the system has reached a steady state. The switch opens at time \( t = 2 \, \text{s} \).

**Tasks:**

(a) Find \( i_a(2^- \, \text{s}) \).

(b) Find \( i_a(t) \) for \( t > 2 \, \text{s} \). Write the equation.

**Circuit Diagram:**

- A current source of \( 6 \, \text{A} \).
- Two resistors in parallel, each of \( 2 \, \Omega \).
- A series circuit with a \( 2 \, \Omega \) resistor, an inductor of \( 12 \, \mu\text{H} \), and the switch.
- The current \( i_a \) flows through the second \( 2 \, \Omega \) resistor and the inductor after the switch is opened.

**Analysis Explanation:**

1. **Steady State Analysis (Before \( t = 2 \, \text{s} \)):**
- Determine the behavior of the circuit when the switch is closed and the system is in steady state.
- Calculate the initial current \( i_a(2^- \, \text{s})\) before the switch opens.

2. **Transient Analysis (After \( t = 2 \, \text{s} \)):**
- Analyze the circuit when the switch is opened and the behavior of the inductor becomes significant.
- Write down the equation for \( i_a(t) \) for \( t > 2 \, \text{s} \).

This analysis involves calculating the current \( i_a \) at both before and after the switch is opened. The equations will describe how the circuit responds due to the inductance when the switch opens.
