Electronic Devices Question 109
Question: In a PN-junction diode
[MP PET 1993]
Options:
A) The current in the reverse biased condition is generally very small
B) The current in the reverse biased condition is small but the forward biased current is independent of the bias voltage
C) The reverse biased current is strongly dependent on the applied bias voltage
D) The forward biased current is very small in comparison to reverse biased current
Show Answer
Answer:
Correct Answer: A
Solution:
In forward biased PN-junction, external voltage decreases the potential barrier, so current is maximum.
While in reversed biased PN-junction, external voltage increases the potential barrier, so the current is very small.
