A) decreases with increase in potential barrier voltage
B) increases with increase in potential barrier voltage
C) independent of potential barrier voltage
D) none of the above
Correct Answer: A
Solution :
In forward biasing, the forward bias voltage opposes the potential barrier \[{{V}_{B}}\]. Due to it, the potential barrier is considerably reduced, the depletion region becomes thin, the potential barrier is much reduced and at some forward voltage (0.1 to 0.3 V), it is eliminated altogether. Note: Since, the small increase in forward voltage shows the large increase in forward current, hence the resistance of p-n junction is low to the flow of current when forward biased.You need to login to perform this action.
