Question

In the diagram shown, the Zener diode has a reverse breakdown voltage \( V_z \). The current through the load resistance \( R_L \) is \( I_L \). The current through the Zener diode is

• A. \( V_o = V_z \)
• B. \( V_o = V_z - I_L R_L \)
• C. \( V_o = V_z \)
• D. \( V_o = V_z - I_L R_L \)

Answer 1

The Correct Option is D

The voltage across the Zener diode is reduced by the voltage drop across the load resistance. The relationship is:\(\ \ V_o = V_z - I_L R_L\)
