**Circuit Analysis and Time Constants**

Consider the circuit shown in the figure below. Let the electromotive force \( \varepsilon = 10.00 \, \text{V} \), the inductance \( L = 12 \, \text{mH} \), and the resistance \( R = 9 \, \Omega \). The circuit diagram includes a battery, a switch \( S \), a resistor \( R \), and an inductor \( L \) in series.

**Key Questions:**
(a) What is the inductive time constant of the circuit?
(b) Calculate the current in the circuit 100 μs after the switch is closed.
(c) What is the value of the final steady-state current?
(d) How long does it take the current to reach 75.0% of its maximum value?

**Explanation of the Diagram:**
- **Battery (\( \varepsilon \)):** Provides a constant voltage of 10.00 V.
- **Switch \( S \):** Controls the flow of current; in this scenario, it is considered to be closed.
- **Resistor \( R \):** With a resistance of 9 Ω, it limits the current flow in the circuit.
- **Inductor \( L \):** With an inductance of 12 mH, it opposes changes in current flow.

This configuration represents a classic series RL circuit, which is essential for analyzing transient response and time constants.
