| Ge and Si diodes start conducting at 0.3 V and 0.7 V respectively. In the following figure if Ge diode connection are reversed, the value of \[{{\text{V}}_{o}}\] by : (assume that the Ge diode has large breakdown voltage) |
 |
A) 0.8 V
B) 0.6 V
C) 0.2 V
D) 0.4 V
Correct Answer: D
Solution :
| \[{{V}_{{{O}_{i}}}}=12-0.3=11.7V\] |
| \[{{V}_{{{O}_{f}}}}=12-0.7=11.3V\] |
| \[\Rightarrow \] \[\Delta {{V}_{O}}=-0.4V.\] |
