**Circuit Problem Explanation for Educational Website**

**Objective:**
Determine the voltage \( v_o(t) \) for the given circuit when the initial current \( i(0) = 6 \, \text{A} \) and the source voltage \( v(t) = 0 \, \text{V} \).

**Circuit Description:**
The circuit consists of:
- A series combination of a 2-ohm resistor (\(2 \, \Omega\)) and a 0.4 H inductor (\(0.4 \, \text{H}\)).
- An input current \( i(t) \) flows into the series combination.
- Parallel to the inductor, there is a 3-ohm resistor (\(3 \, \Omega\)).
- The output voltage \( v_o(t) \) is measured across the 3-ohm resistor.

**Equation to Solve:**
The output voltage \( v_o(t) \) is given by the equation:
\[
v_o(t) = v_o(0) \, e^{-t/\tau}
\]
where:
- \( v_o(0) \) is the initial voltage across the 3-ohm resistor.
- \( \tau \) is the time constant of the circuit.

**Tasks:**
- Determine the initial voltage \( v_o(0) \).
- Calculate the time constant \( \tau \).

Please fill in the calculated values:
- \( v_o(0) = \boxed{\,\,\,} \, \text{V} \)
- \( \tau = \boxed{\,\,\,} \, \text{s} \)

**Conclusion:**
This exercise involves analyzing a simple RL circuit to determine its transient response using initial conditions and the time constant formula.
