Question
**Problem 14.15**: Determine the maximum power transferred to \( Z_L \) in the circuit shown in Figure 14-31.

**Figure 14-31**: Circuit schematic for problem 14.15.

**Description of the Circuit Diagram:**

1. **Resistors and Inductors:**
   - A 6 Ω resistor is connected in series with a j8 Ω inductor. The current through this branch is labeled as \( I_x \).

2. **Independent Source:**
   - A current source of \( 2 \angle 0^\circ \, \text{A}_{\text{rms}} \) is shown, with its positive terminal connected to the node between the 6 Ω resistor and the dependent source.

3. **Dependent Source:**
   - A dependent voltage source \( 2I_x \) is connected in parallel with the 6 Ω resistor and the inductor. It is oriented such that the positive polarity is on top.
  
4. **Additional Resistors:**
   - A 6 Ω resistor is connected in series with a 7 Ω resistor. This series combination is in parallel with the dependent source.

5. **Load Impedance \( Z_L \):**
   - The load impedance \( Z_L \) is connected across the 7 Ω resistor.

The objective is to determine the maximum power transferred to \( Z_L \) using the given circuit configuration.
