Consider the following statements (A) and (B) and identify the correct answer:
(A) A zener diode is connected in forward bias, when used as a voltage regulator.
(B) The potential barrier of p-n junction lies between 0 V to 0.1 V.
(A) A zener diode is connected in forward bias, when used as a voltage regulator.
(B) The potential barrier of p-n junction lies between 0 V to 0.1 V.
View answer and explanation
Correct option: A
(A) and (B) both are incorrect
Option A ((A) and (B) both are incorrect) is correct because a Zener diode is used in reverse bias as a voltage regulator, and the potential barrier for a p-n junction is typically around 0.3V for Germanium and 0.7V for Silicon.
