diodes start conducting at

0.3V

and

0.7V

respectively. In the following figure if

Ge

diode connection are reversed, the value of

{V}_{0}

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

Ge and Si diodes start conducting at 0.3V and 0.7V respectively. In the following figure if Ge diode connection are

Ge and Si diodes start conducting at 0.3V and 0.7V respectively. In the following figure if Ge diode connection are

Options

A $0.8V$
B $0.4V$
C $0.2V$
D $0.6V$

Correct answer

B. $0.4V$

Step-by-step solution

In first case,

{V}_{0} = \left(12 - 0.3\right)V = 11.7V

In second case,

{V}_{0} = \left(12 - 0.7\right)V = 11.3V

∆ {V}_{0} = 0.4V
