The two diodes A and B are biased as shown, then
-5V A -9V
-3V B -6V

A

The diodes A and B are reverse biased

B

The diode A is forward biased and B is reverse

C

The diode B is forward biased and A is reverse biased

D

The diodes A and B are forward biased

Text Solution

Verified by Experts

The correct Answer is:
D
the potential voltages of diode A are as follows,
For p-type, `V_(1) = -5 V`
For n-type, `V_(2) = -9 V`
It can be observed that for diode A, `V_(1) > V_(2)`
Hence, the diode is in forward bias
The potential voltages of diode B are as follows,
For p-type, `V_(1) = -3 V`
For n-type, `V_(2) = -6 V`
It can be observed that for diode A, `V_(1) > V_(2)`
Hence, the diode is in forward bias.
