Hello there. I think I am doing this wrong. Could you guide me through it? Thank you 

 

**Title: Understanding Zener Regulator Load Current** **Question:** What is the maximum load current \( I_L \) that can be drawn from the Zener regulator in Fig. P3.77 if it is to maintain a regulated output? What is the minimum value of \( R_L \) that can be used and still have a regulated output voltage? **Diagram Explanation:** The diagram in Figure P3.77 presents a circuit featuring a Zener regulator. Key components include: - A 30V DC supply connected in series with a 15 kΩ resistor. - A Zener diode with specifications \( V_Z = 9V \) (Zener voltage) and \( R_Z = 0 \) (Zener impedance). - The load resistor \( R_L \) connected in parallel with the Zener diode, where the load current \( I_L \) flows through \( R_L \). **Objective:** To determine the maximum load current \( I_L \) that maintains the regulation at the Zener voltage. Additionally, ascertain the minimum value of \( R_L \) that allows for this regulated voltage. This exercise is crucial in understanding the functioning and limitations of Zener diode regulators in electrical circuits.
