Consider the following statements A and B and identify the correct answer-
[A] A Zener diode is always connected in reverse bias.
[B] The potential barrier of a P-N junction lies between 0.1 to 0.3 V approximately.
Text Solution
Verified by ExpertsThe correct answer is:
C
When Zener diode is forward biased, it behaves like ordinary diode and when reverse biased, it will be a voltage stabilizer. Also, at room temperature, the voltage across the depletion layer for silicon is about 
and for germanium is about 
Hence, statement 
is correct but statement 
is wrong.
