For the circuit showing below, the current through the Zener diode is: |
|||
(a) |
5 mA |
(b) |
Zero |
(c) |
14 mA |
(d) |
9 mA |

9 mA |
Assuming Zener diode does not undergo
Breakdown, current in circuit==8mA
∴voltage drop across diode=80 V50 V. The diode undergo breakdown.
Current is R1==14mA
Current is R2==5 mA
∴Current through diode=9mA
