Zener diode is used for:
  • A
    Amplification
  • B
    Rectification
  • C
    Stabilisation
  • D
    All of the above
✓

Answer

  1. Stabilisation

Explanation:

A zener diode is always operated in its reverse biased condition. A voltage regulator circuit can be designed using a zener diode to maintain a constant DC output voltage across the load in spite of variations in the input voltage or changes in the load current. The zener voltage regulator consists of a current limiting resistor RS​ connected in series with the input voltage VS​ with the zener diode connected in parallel with the load RL in this reverse biased condition.Hence we can say that ,zener diode is used for stabilization.
