**Transcription for Educational Website:** --- **Problem Statement:** **(1)** For \( t < 2 \, \text{s} \), the switch is closed and you may assume the system has reached steady state. **The switch opens at time \( t = 2 \, \text{s} \).** **(a)** Find \( i_b(2^-) \). **(b)** Find \( i_b(t) \) for \( t > 2 \, \text{s} \). **Diagram Explanation:** The circuit diagram below illustrates the system in question. - The circuit includes a 24 \(\mu\text{H}\) inductor and two resistors, one of 6 \(\Omega\) and another of 3 \(\Omega\). - A dependent current source is marked as \( 5i_a \) where \( i_a \) is the current through the 6 \(\Omega\) resistor. - There is a switch that opens at \( t = 2 \). - A 6 V voltage source is present in the circuit. - The current \( i_a \) flows through the 6 \(\Omega\) resistor, and \( i_b \) flows through the 3 \(\Omega\) resistor. - The goal is to analyze the behavior of \( i_b \) right before the switch opens, denoted by \( i_b(2^-) \), and after the switch opens for \( t > 2 \). --- This transcription is intended to guide students through analyzing the circuit's response to the switch opening, emphasizing concepts of steady state and transient analysis in electrical circuits.
