**Problem 2.** 

In the circuit below, find \( Z_L \) for maximum power transfer to the load. Also, find the value of maximum power transferred to the load.

### Circuit Description:

The circuit diagram consists of the following components:

1. **Voltage Source:** 
   - \( 12 \angle 0^\circ \) volts

2. **Resistors and Inductors:**
   - \( 3 \, \Omega \) resistor in series with the voltage source
   - \( j2 \, \Omega \) inductor in series with the \( 3 \, \Omega \)
   - \( 4 \, \Omega \) resistor in parallel to another section of the circuit

3. **Current Source:**
   - \( 3 \angle 10^\circ \) amperes

4. **Load Impedance (\( Z_L \)):**
   - Positioned between the \( 4 \, \Omega \) resistor and the \( 3 \angle 10^\circ \) A current source

5. **Additional Components:**
   - \( j3 \, \Omega \) inductor in series with the \( 6 \angle 0^\circ \) volts source

### Analysis Task:

1. **Determine \( Z_L \):** 
   - For maximum power transfer, \( Z_L \) should be the complex conjugate of the Thevenin equivalent impedance of the rest of the circuit.

2. **Calculate Maximum Power Transfer:**
   - Analyze the circuit using Thevenin’s theorem to derive and calculate the maximum power delivered to \( Z_L \).

This setup involves analyzing complex impedances and applying principles of AC circuit analysis, including phasors and Thevenin’s theorem, to optimize power transfer.
