Question
**Example 3.** Assume that there is no initial energy stored in the following circuit at \( t = 0 \), and that \( i_s(t) = 10 \, u(t) \).

a) Find \( V_o(s) \) using Thevenin’s theorem.  
b) Apply the initial-value and the final-value theorems to find \( v_o(0) \) and \( v_o(\infty) \).

**Circuit Diagram Overview:**

- There is a current source \( i_s(t) \) providing \( 10 \, u(t) \) amperes.
- The circuit contains two resistors, \( R_1 \) and \( R_2 \), both with a resistance of \( 5 \, \Omega \).
- A dependent current source \( 2i_x \) is present, where \( i_x \) is the current through \( R_1 \).
- An inductor with an inductance of \( 2 \, \text{H} \) is connected to the branch marked by nodes \( a \) and \( b \).
- \( v_o(t) \) is the output voltage across \( R_2 \).

This example involves calculating the Thevenin equivalent circuit and using the initial and final value theorems to determine specific transient and steady-state responses.
