Question

Hello. I appreciate your time and help on my questions. 

Thank you. 

**Problem Statement:** What is the power dissipation in the Zener diode in Fig. P3.77 for: (a) \( R_L = 2 \, \text{k}\Omega \) (b) \( R_L = 4.7 \, \text{k}\Omega \) (c) \( R_L = 15 \, \text{k}\Omega \) (d) \( R_L = \infty \) **Figure P3.77 Description:** The circuit diagram in Figure P3.77 consists of the following components: - A 30 V DC voltage source connected in series with a 15 kΩ resistor. - This series circuit is connected to a parallel branch containing a Zener diode and a load resistor \( R_L \). - The Zener diode has a Zener voltage \( V_Z = 9 \, \text{V} \) and an internal resistance \( R_Z = 0 \). - \( I_L \) represents the current flowing through the load resistor \( R_L \). The task is to determine the power dissipation across the Zener diode for different values of \( R_L \).
