- How to solve this problem- In a PN-junction diode
In a PN-junction diode
- Option 1)
The current in the reverse biased condition is generally very small
- Option 2)
The current in the reverse biased condition is small but the forward biased current is independent of the bias voltage
- Option 3)
The reverse biased current is strongly dependent on the applied bias voltage
- Option 4)
The forward biased current is very small in comparison to reverse biased current
Answers (1)
P -N junction as diode -
It is a one way device. It offers a low resistance when forward biased and high resistance when reverse biased.
- wherein
R = 0, Forward
R Reverse
In forward biased condition resistance produced by P-N junction diode is very small and hence current is very large. In Reserve Biased condition ,resistance is very high and hence current is very small
Option 1)
The current in the reverse biased condition is generally very small
Correct
Option 2)
The current in the reverse biased condition is small but the forward biased current is independent of the bias voltage
Incorrect
Option 3)
The reverse biased current is strongly dependent on the applied bias voltage
Incorrect
Option 4)
The forward biased current is very small in comparison to reverse biased current
Incorrect
