Question

When the Zener diode is used as a voltage regulator, it is connected in

• A. forward bias and in parallel with load.
• B. reverse bias and in series with load.
• C. forward bias and in series with load.
• D. reverse bias and in parallel with load.

Hint:

A Zener regulator uses reverse bias and is connected in parallel with the load.

Answer 1

The Correct Option is D

Step 1: Recall the regulator circuit
Source, series resistor, then the Zener across the load.

Step 2: Bias
The Zener is reverse biased to use its breakdown region, option (D).

Final Answer:
Reverse bias and parallel, option (D). \[ \boxed{\text{Reverse bias, parallel}} \]
