**Problem Statement**

**Q:** Find the reactance of the inductor \( X_L \) in Ohms.

**Input Box:** [A rectangle input box for users to input their answers.]

---

On this page, users are asked to find the reactance of an inductor, denoted as \( X_L \), and express it in Ohms. The reactance of an inductor can be calculated using the formula:

\[ X_L = 2 \pi f L \]

Where:
- \( X_L \) is the inductive reactance in Ohms (Ω)
- \( f \) is the frequency of the AC signal in Hertz (Hz)
- \( L \) is the inductance in Henrys (H)

Users should input their answers in the provided rectangular input box.

### LRC Series Circuit Calculation

An LRC series circuit is defined by the following parameters:
- Inductance \( L = 170. \) mH (millihenries)
- Resistance \( R = 36.0 \) Ohms
- Voltage source \( V = 120. \) V (rms)
- Frequency \( f = 60.0 \) Hz
- Root mean square (rms) current \( I_{rms} = 2.00 \) A 

### Understanding the components:
- **Inductance (L):** It is the property of the circuit that opposes changes in current. 
- **Resistance (R):** It is the property that opposes the flow of current, causing energy dissipation as heat.
- **Voltage source (V):** It provides the necessary electrical potential difference to drive the current through the circuit.
- **Frequency (f):** It is the number of cycles per second of the alternating current (AC).
- **RMS Current (\( I_{rms} \)):** It represents the effective value of varying current as if it were a constant direct current.

### Explanation of Concepts:
1. **Inductor (L):**
   - When AC flows through the inductor, it creates an inductive reactance (\( X_L \)) that resists the change in current. The inductive reactance is given by \( X_L = 2\pi f L \).

2. **Resistor (R):**
   - The resistor provides resistance to current, and the voltage drop across the resistor is in phase with the current.

3. **Capacitor (C):**
   - Although the capacitance is not mentioned here, capacitors typically create capacitive reactance (\( X_C \)) in AC circuits, given by \( X_C = \frac{1}{2\pi f C} \).

4. **Total Impedance (Z):**
   - In an LRC circuit, the total impedance follows the relationship \( Z = \sqrt{R^2 + (X_L - X_C)^2 } \). 
   - For the given circuit, based on the provided information, we assume capacitive reactance is negligible or not present.

### Calculations:
1. **Calculating Inductive Reactance (\( X_L \))**:
   \[ X_L = 2\pi f L \]
