Ge and Si diodes start conducting at 0.3V and 0.7V respectively. In the following figure if Ge diode connection are reversed, the value of V0 changes by:
(assume that the Ge diode has large breakdown voltage)
0.4 V
0.6 V
0.8 V
0.2 V
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
before reversing
(Since threshold voltage of
<
, so
conducts)
afer reversing
is reverse biased , so
conducts current
0.4 V
Option 2)0.6 V
Option 3)0.8 V
Option 4)0.2 V
