Question

I need to solve it in  S-DOMAIN

**Problem Statement:**

In the circuit below, 

(a) Find the expression of \( V_o(S) \). 

(b) Find the expression for \( v_o(t) \) for \( t \geq 0 \).

**Circuit Description:**

- The circuit is a series-parallel combination consisting of:
  - A 100 V DC voltage source.
  - A 5 kΩ resistor connected in series with the voltage source.
  - A switch \( t = 0 \) which toggles between positions 'a' and 'b'.
  - A 10 µF capacitor connected in parallel.
  - An inductor of 60 mH in series with the capacitor, forming an LC circuit.
  - A controlled current source providing \( 15i \) (depending on a variable \( i \)).
  - A 200 Ω resistor in series with the controlled source.
  - An 80 Ω resistor, which is in parallel with the controlled source and the 200 Ω resistor.

**Analysis Required:**

1. **Laplace Transform Analysis:**
   - Determine the expression for \( V_o(s) \) in the s-domain, which involves using the Laplace transform to analyze the circuit components and their relationships.

2. **Time Domain Analysis:**
   - Find the expression for \( v_o(t) \) for \( t \geq 0 \), using inverse Laplace transform techniques or solving differential equations as required.

The circuit incorporates elements of transient analysis involving the capacitor and inductor, and it also features a current-dependent source, making it a problem suitable for advanced circuit analysis techniques.
