- Can someone explain PN-junction diode works as an insulator, if connected
PN-junction diode works as an insulator, if connected
- Option 1)
To A.C.
- Option 2)
In forward bias
- Option 3)
In reverse bias
- Option 4)
None of these
Answers (1)
As we learnt in
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
P N Junction in reverse biased mode offer infinitely large resistance and hence no current flow through it. Hence P N Junction in reverse bias act as an insulator.
Option 1)

Option 3)
In reverse bias
Correct
Option 4)
