In the circuit shown in figure, the silicon and germanium diodes start conducting at 0.7 V and 0.3 V respectively. What are the values of `V_0` and I?

A

12 V, 2.4 mA

B

11.7 V, 2.34 mA

C

11.3 V, 2.26 mA

D

11 V, 2.2 mA

Text Solution

Verified by Experts

The correct Answer is:
B
The germanium diode will start conducting before the silicon diode does so. The voltage across Ge = 0.3 V. The output voltage `V_0` is the voltage across R= 12 -0.3 = 11.7 V
The current I =`(11.7 V)/(5 kOmega)=11.7/(5xx10^3)`
`=2.34xx10^(-3)A=2.34 mA`
