Ge and Si diodes conduct at \(0.3 \,V\) and \(0.7\, V\) respectively. In the following figure if Ge diode connection are reversed, the valve of \(V0\) changes by.....\(V\)
- A \(0.2\)
- B \(0.4\)
- C \(0.6\)
- D \(0.8\)
Answer & Solution
Correct Answer
(B) \(0.4\)
Step-by-step Solution
Detailed explanation
Consider the case when \( Ge\) and \(Si \) diodes are connected as show in the given figure. Equivalent voltage drop across the combination \(Ge\) and \(Si\) diode \(= 0.3 \,V\) ==> Current \(i = \frac{{12 - 0.3}}{{5\,k\Omega }} = 2.34\,mA\) Out put voltage…
