MCQ
For the circuit shown below, the current through the Zener diode is......$mA$
- ✓$9$
- B$5$
- C$0$
- D$14$
✓
Answer
Correct option: A.
$9$
a
$\mathrm{I}_{10 \mathrm{k}}=\frac{50}{10 \mathrm{k}}=5\, \mathrm{mA}$
$\mathrm{I}_{10 \mathrm{k}}=\frac{50}{10 \mathrm{k}}=5\, \mathrm{mA}$
$\mathrm{i}_{5 \mathrm{k}}=\frac{120-50}{5 \mathrm{k}}=14\, \mathrm{mA}$
$\mathrm{i}_{2}=(14-5) \mathrm{mA}=9\, \mathrm{mA}$
