Question 94 of 209

GeGe and SiSi diodes start conducting at 0.3V0.3V and 0.7V0.7V respectively. In the following figure if GeGe diode connection are reversed, the value of V0{V}_{0} changes by: (assume that the Ge diode has large breakdown voltage)

Show answer and solution

Answer: (B) 0.4V0.4V

In first case, V0=(12−0.3)V=11.7V{V}_{0}=\left(12-0.3\right)V=11.7V

In second case,
V0=(12−0.7)V=11.3V{V}_{0}=\left(12-0.7\right)V=11.3V

∆V0=0.4V∆{V}_{0}=0.4V
