In the diagram shown, the Zener diode has a reverse breakdown voltage of V_Z . The current through the load resistance R_L is I_L . The current through the Zener diode is

Options

  1. AV₀-V_Z R_S
  2. BV₀-V_Z R_L
  3. CV_Z R_L
  4. D( V₀-V_Z R_S )-I_L

Correct answer

D. ( V₀-V_Z R_S )-I_L

Step-by-step solution

From the diagram, I=I_Z+I_L I_Z=I-I_L= V_O-V_Z R_S -I_L
