Options

  1. Aforward bias and in parallel with load.
  2. Breverse bias and in series with load.
  3. Cforward bias and in series with load.
  4. Dreverse bias and in parallel with load.

Correct answer

D. reverse bias and in parallel with load.

Step-by-step solution

A Zener diode is used as a voltage regulator to provide a constant voltage across a load. To operate in the Zener breakdown region, the diode must be connected in reverse bias. To ensure the voltage across the load remains constant and equal to the Zener voltage, it is connected in parallel with the load. Answer: reverse bias and in parallel with load.
