Question 48

Electronics

Zener diode is used for

  1. A.current amplification.
  2. B.power amplification.
  3. C.voltage regulation.
  4. D.energy conversion.
Show the answer and explanation

Answer: C (voltage regulation.)

Explanation

In reverse breakdown a Zener diode keeps an almost constant voltage across itself even when the current changes, so it is used to regulate (stabilise) voltage.
