Question

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.

(1) (A) and (B) both are correct.

(2) (A) and (B) both are incorrect.

(3) (A) is correct and (B) is incorrect.

(4) (A) is incorrect but (B) is correct.

Answer 1

Option : (3) (A) is correct and (B) is incorrect.

Reverse bias Zener diode use as a voltage regulator for Ge Potential barrier V₀ = 0.3 V 

Si Potential barrier V₀ = 0.7 V
