Q. Consider the following statements (A) and (B) and identify the correct answer. (A) A zener diode is Connected in reverse bias, when used as a voltage regulator. (B) The potential barrier of p-n junction lies between 0.1 V to 0.3 V.
A) (A) and (B) both are incorrect.
B) (A) is correct and (B) is incorrect.
C) (A) is incorrect but (B) is correct.
D) (A) and (B) both are correct.
Explanation
[Solution] A zener regulator works in reverse bias (A correct). The barrier potential is about 0.3 V (Ge) to 0.7 V (Si), not 0.1-0.3 V (B incorrect). Answer (2).
