MCQ
Zener diode works on:
  • A
    Zero bias
  • ✓
    Reverse bias
  • C
    Forward bias
  • D
    Infinite bias
✓

Answer

Correct option: B.
Reverse bias
We know that zener diode works on the reverse bias. When the reverse bias is equal to the break$-$down voltage, the voltage across the zener remains almost constant and the current increases rapidly.
