(A) Calculate the value of `V_(0)` and `i` if the silicon and germanium diode start conducting at 0.7 V and 0.3 V respectively.
(B) If the Ge diode connection is now reversed, what will be the new values of `V_(0)` and `i` ?

Explanation

`V_(0)=23-0.3=11.7 V rArr` Current `I=(V)/(R_(L))=(11.7)/(5 xx 10^(3))=2.34 mA`
On reversing the connection of Ge diode the output voltage
`V_(0)=12-0.7 =11.3 V`
The current in load `I'=(V'_(0))/(R_(L))=(11.3)/(5 xx 10^(3))=2.26 mA`
