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.
Detailed Solution
A Zener diode is used as a voltage regulator in reverse bias – (A) is correct.
The potential barrier of a p-n junction is about 0.3 V for Ge and 0.7 V for Si, not 0.1–0.3 V – (B) is incorrect.
So (A) is correct and (B) is incorrect.
