For the circuit shown in the figure, determine the current through the Zener diode (Given: Zener diode is at break down voltage V z = 5.6 V )

Options

  1. A5 mA
  2. B17 mA
  3. C10 mA
  4. D7 mA

Correct answer

C. 10 mA

Step-by-step solution

i 1 - i 2 = V z 800 = 5.6 800 = 7 mA For loop ABCF , 9 - 200 i 1 - V z = 0 i 1 = 0.017 or 17 mA i 2 = i 1 - 7 mA = 10 mA
