Determine the step response v(t) for t > 0 in the circuit below.

*Please do not use Laplace transform technique, as we are only on RLC circuits transformation chapter (beginning)

### Circuit Analysis for Educational Purposes

This illustration represents a simple electrical circuit. Let's break down the components:

1. **Voltage Sources**: 
   - An **8 V** voltage source is connected in series with a **12 V** voltage source. These provide the electrical energy to the circuit.

2. **Resistor**:
   - The circuit includes a **2 Ω** resistor. Resistors are components that oppose the flow of electric current, causing a drop in voltage.

3. **Inductor**:
   - A **1 H** (henry) inductor is present. Inductors store energy in a magnetic field when electric current flows through them. They oppose changes in current.

4. **Capacitor**:
   - There is a capacitor with a capacitance of **1/5 F** (farad). Capacitors store energy in an electric field, and they resist changes in voltage.

5. **Switch**:
   - A switch is included, indicating the circuit's operation initiates at **t = 0**. When closed, it allows current to flow and the circuit to function.

### Understanding the Diagram

- The diagram visually shows the circuit connections and components. It uses standard symbols:
  - **Circles with + and - signs** represent voltage sources.
  - **Zigzag line** denotes a resistor.
  - **Coil shape** represents an inductor.
  - **Parallel lines** indicate a capacitor.
  
- The positive and negative signs on the voltage and capacitor signify polarity.
  
### Key Concepts

- **Initial Conditions**: At **t = 0**, the circuit behavior starts to change as the switch moves to the closed position.
- **Energy Storage**: Both the capacitor and inductor can store energy and release it over time, affecting the transient response of the circuit.
- **Circuit Dynamics**: The resistor, inductor, and capacitor work together to define the circuit’s time-dependent behavior as it reaches a steady state. 

This setup is typical for studying the transient response and analyzing the step response of RLC circuits in educational environments.
