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 V0 changes by: (assume that the Ge diode has large breakdown voltage)

  1. 0.8 V
  2. 0.4 V
  3. 0.2 V
  4. 0.6 V

Solution

In first case, V0=12-0.3V=11.7 V

In second case, V0=12-0.7V=11.3 V

∆V0=0.4 V
